EXHIBIT 10.13
                         1997 EMPLOYEE STOCK OPTION PLAN
                                       OF
                             ADVANCED PHOTONIX, INC.

          (As adopted by the Board of Directors as of January 14, 1997)


1. The Plan.  This 1997  Employee  Stock Option Plan (the "Plan") is intended to
encourage ownership of stock of Advanced Photonix, Inc. (which together with its
subsidiaries  is  hereinafter  referred to as the  "Corporation")  by  specified
employees  of,  and  consultants  and  advisors  to,  the  Corporation  and  its
subsidiaries and to provide additional incentive for them to promote the success
of the business of the Corporation.

2. Stock Subject to the Plan.  Except as otherwise  provided  herein,  the total
number of shares of Class A Common  Stock,  par value  $.001 per  share,  of the
Corporation  (the  "Stock")  which may be issued  pursuant  to the  exercise  of
options granted hereunder  ("Options") shall be 1,000,000.  Such shares of Stock
may be in whole or in part,  either  authorized and unissued  shares or treasury
shares as the Board of Directors of the  Corporation  (the  "Board")  shall from
time to time  determine.  If an Option shall expire or terminate  for any reason
without having been exercised in full, the  unpurchased  shares covered  thereby
shall  (unless  the Plan  shall have been  terminated)  again be  available  for
Options under the Plan.

3.  Administration  of the Plan. The Plan shall be  administered  by a committee
(the  "Committee")  composed  of two or more  non-employee  members of the Board
which  shall  have  plenary  authority,  in its  discretion,  to  determine  the
employees of the  Corporation  and its  subsidiaries  to whom  Options  shall be
granted  ("Optionees"),  the  number  of  shares to be  subject  to each  Option
(subject to the  provisions  of  Paragraph  2), the option  exercise  price (the
"Exercise  Price")  (subject  to the  provisions  of  Paragraph  7), the vesting
schedule of each option,  whether an Option is intended to be an incentive stock
option within the meaning of Section 422 of the Internal Revenue Code (an "ISO")
or whether it is intended  not to be an ISO (a "Non ISO") and the other terms of
each Option.  The  Committee  shall hold meetings at such times and places as it
may  determine.  Acts  approved at a meeting by a majority of the members of the
Committee or acts approved in writing by the unanimous consent of the members of
the Committee shall be the valid acts of the Committee. The Committee shall have
plenary  authority,  subject to the express provisions of the Plan, to interpret
the Plan, to prescribe,  amend and rescind any rules and regulations relating to
the Plan and to take such other action in  connection  with the Plan as it deems
necessary or advisable.  The interpretation and construction by the Committee of
any  provisions of the Plan or of any Option granted  thereunder  shall be final
and no member of the Committee  shall be liable for any action or  determination
made in good faith with respect to the Plan or any Option granted  thereunder by
the Committee.

4. Employees Eligible for Options. All employees of and consultants and advisors
to, the Corporation  shall be eligible for Options.  In making the determination
as to  persons  to whom  Options  shall be  



granted, the number of shares to be covered by such Options, and the other terms
and  conditions  of the Option,  the  Committee  shall take into  account  their
duties,  their  present  and  potential  contributions  to  the  success  of the
Corporation  and such other factors as it shall deem relevant in connection with
accomplishing the purpose of the Plan.

5. Term of Plan.  The Plan shall  terminate  on, and no Options shall be granted
after,  January 13, 2007 provided  that the Committee may at any time  terminate
the Plan prior thereto.

6. Maximum  Option  Grant.  Subject to the  provisions  of Section 2 above,  the
number of shares of Stock for which any individual may be granted  Options shall
be unlimited.

7. Exercise Price.  Each Option shall state the exercise  price,  which shall be
such price as the Committee in its discretion may determine  provided,  however,
that in the case of ISOs,  the exercise price shall be not less than 100% of the
fair market  value of the Stock on the date of the  granting of the Option,  nor
less than 110% of such fair  market  value in the case of an ISO  granted  to an
individual  who,  at the  time  the  Option  is  granted,  is a 10%  Holder  (as
hereinafter  defined).  The fair  market  value  of  shares  of  Stock  shall be
determined  by the  Committee and shall be (i) the closing price of the Stock on
the date of the  granting  of the  Option if the Stock is traded on a  regulated
securities exchange, or (ii) if not traded on such an exchange, the mean between
the high bid and low  asked  prices  on such date as  reported  by a  recognized
over-the-counter reporting source.

8. Term of Options. The term of each Option granted under this Plan shall be for
a maximum of ten years from the date of granting thereof,  and a maximum of five
years in the case of an ISO  granted  to a 10%  Holder,  but may be for a lesser
period or be subject to earlier termination as hereinafter provided.

9. Exercise of Options. Except as otherwise provided by the Committee, an Option
may be  exercised  from time to time as to any part or all of the Stock  covered
thereby,  provided,  however, that an Option may not be exercised (a) as to less
than 100  shares  at any time (or as to less  than  the  remaining  shares  then
purchasable  under the Option,  if less than 100  shares),  and (b) prior to the
expiration  of at least six months from the date of grant.  The  Exercise  Price
shall be paid in full at the time of the  exercise  of an Option  (i) in cash or
(ii) by the  transfer  to the  Corporation  of shares  of its Stock  with a fair
market value (as determined by the Committee) equal to the purchase price of the
Stock  issuable upon exercise of such Option.  The holder of an Option shall not
have any  rights  as a  stockholder  with  respect  to the Stock  issuable  upon
exercise  of an  Option  until  certificates  for such  Stock  shall  have  been
delivered to him after the exercise of the Option.

10.  Non-Transferability  of  Options.  Except  as  provided  in  the  following
sentence, an Option shall not be transferable otherwise than by will or the laws
of descent  and  distribution  and is  exercisable  during the  lifetime  of the
employee  only by him or his guardian or legal  representative.  Options will be
transferable to members of an Optionee's immediate family,  including trusts for
the benefit of such family members and partnerships in which such family members
are the only partners ("Permitted  Transferees").  A transferred Option would be
subject to all of the same terms and  conditions  as if such Option had not been
transferred.


11. Form of Option.  Each Option granted pursuant to the Plan shall be evidenced
by an agreement (the "Option Agreement") which shall clearly identify the status
of the Options granted  thereunder  (i.e.,  whether an ISO or Non-ISO) and which
shall be in such form as the  Committee  shall  from time to time  approve.  The
Option  Agreement  shall comply in all respects with the terms and conditions of
the  Plan  and  may  contain  such  additional  provisions,  including,  without
limitation, restrictions upon the exercise of the Option, as the Committee shall
deem advisable.

12.  Termination of Options.  No Option shall be exercisable  after the first to
occur of the following:

a.   Expiration  of the Option term  specified in the Option,  which in no event
     shall exceed (A) ten years from the date of grant, or (B) in the case of an
     ISO granted to an Optionee who is a 10% Holder, five years from the date of
     the grant;

b.   Six months  following the date the Optionee ceases to be an employee of the
     Company for any reason; or

c.   The date, if any, set by the Committee to be an accelerated expiration date
     pursuant to the provisions of Paragraph 17 below.

13.  Cessation of Employment.  For purposes of the Plan, the  termination of the
contractual  relationship  between the  Corporation  and a consultant or advisor
shall be deemed a termination or cessation of employment.

14. Limit on Exercise of Incentive  Stock  Options.  The  aggregate  Fair Market
Value (determined as of the time Options are granted) of the Shares with respect
to which Incentive Stock Options may first become  exercisable by an Optionee in
any one calendar year under the Plan and under any other plan of the Corporation
or an  affiliate  of the  Corporation,  shall not  exceed  $100,000.  The limits
imposed by this Paragraph 9 shall apply only to Incentive  Stock Options granted
under  the  Plan,  and not to any  other  Options.  In the  event an  individual
receives  an  Option   intended  to  be  an  Incentive  Stock  Option  which  is
subsequently  determined to have  exceeded the limit set forth above,  or if any
individual  is  granted  an  Option  intended  to be an ISO that  first  becomes
exercisable  in a calendar  year for Option  Shares that have an aggregate  fair
market value  (determined as of the time the Options are granted)  exceeding the
limits set forth  above,  the Options  for Option  Shares in excess of the limit
shall be treated as non-ISOs.

15. Stock Dividends or  Recapitalization.  In the event of a stock dividend paid
in shares of the class of stock subject to any Option outstanding hereunder,  or
recapitalization,  reclassification,  split-up  or  combination  of shares  with
respect  to said  class of stock,  the  Committee  shall  have the power to make
appropriate  adjustments  of the  exercise  price  under such  option and of the
number and kind of shares as to which such  Option is then  exercisable,  to the
end that the Optionee's proportionate interest shall be maintained as before the
occurrence of such event,  and in any case an appropriate  adjustment shall


also be made in the total  number and kind of shares of stock  reserved  for the
future  granting of options  under this Plan.  Any such  adjustment  made by the
Committee  pursuant  to this  Plan  shall be  binding  upon the  holders  of all
unexpired option rights outstanding hereunder.  Anything in the foregoing to the
contrary  notwithstanding,  no such adjustment shall be made with respect to any
option which is an ISO without the consent of the Optionee,  if such  adjustment
would be a modification  of such option within the meaning of subsection  425(h)
of the Internal Revenue Code.
 
16. Mergers, Consolidation, Reorganization, Etc. If the Corporation shall become
a party to any corporate merger,  agreement for the sale of substantially all of
its assets and property, separation or reorganization,  the Committee shall have
the power to make  appropriate  arrangements,  which  shall be binding  upon the
holders of unexpired option rights,  for the substitution of new options for any
unexpired options then outstanding under this Plan, or for the assumption of any
such unexpired options,  which in the opinion of the Committee maintain,  to the
maximum extent practicable,  the Optionee's proportionate interest as before the
occurrence of such event;  provided,  however, that such arrangements shall meet
the requirements of subsections 422A (with respect to ISOs) and 425(h)(a) of the
Internal Revenue Code.

17.  Liquidation or Dissolution of the Corporation.
 
a.   In the event of the dissolution or liquidation of the Corporation,  whether
     voluntary or otherwise,  and unless in connection therewith the obligations
     of the Corporation  under all  outstanding  options granted under this Plan
     have been assumed or replaced in  accordance  with  Section 16 hereof,  all
     options  outstanding under this Plan shall be exercised,  if at all, within
     the ninety day period  commencing on the date specified in subparagraph (b)
     below and shall be exercisable  only to the extent of, and with respect to,
     any or all shares for which  they  could  have been  exercised  immediately
     prior to such date. All options not exercisable prior to the date specified
     in  subparagraph  (b) shall  terminate  upon  such  date,  and all  options
     exercisable  immediately  prior  to such  date  shall,  to the  extent  not
     exercised within the ninety-day period  commencing on such date,  terminate
     at the end of such ninety-day period.

b.   The date specified in this  subparagraph (b) is the date of the earliest to
     occur of the following events:
 
     i.   The  entry,  in a court  having  jurisdiction,  of an  order  that the
          corporation be liquidated or dissolved;

     ii.  Adoption  by the  shareholders  of  the  Corporation  of a  resolution
          resolving that the corporation be liquidated or dissolved voluntarily;
          or

     iii. Adoption by the shareholders of the Corporation of a resolution to the
          effect  that the  Corporation  cannot,  by reason of its  liabilities,
          continue  its  business  and  that it is  advisable  to  liquidate  or
          dissolve the Corporation.


18.  Shareholder  and Stock  Exchange  Approval.  This Plan is subject to and no
Options shall be exercisable  hereunder  until after the approval by the holders
of a majority of the Stock of the  Corporation  voting at a duly held meeting of
the  stockholders of the Corporation  within twelve months after the date of the
adoption of the Plan by the Board.

19.  Amendment of the Plan. The Board shall have complete power and authority to
modify or amend the Plan  (including the form of Option  Agreement) from time to
time in such respects as it shall deem advisable;  provided,  however,  that the
Board shall not, without the approval of the votes  represented by a majority of
the  outstanding  Stock of the  Corporation  present or represented at a meeting
duly  held  in  accordance  with  the  applicable  laws  of  the   Corporation's
jurisdiction of incorporation  and entitled to vote at a meeting of stockholders
or by the written consent of stockholders  owning stock  representing a majority
of the votes of the  corporation's  outstanding  stock, (i) increase the maximum
number of shares which in the  aggregate  are subject to Options  under the Plan
(except as provided by  Paragraph  15),  (ii) extend the term of the Plan or the
period  during  which  Options  may be granted or  exercised,  (iii)  reduce the
Exercise  Price,  in the  case of ISOs  below  100%  (110% in the case of an ISO
granted to a 10% Holder) of the fair  market  value of the Stock  issuable  upon
exercise of Options at the time of the  granting  thereof,  other than to change
the manner of  determining  the fair market  value  thereof,  (iv)  increase the
maximum number of shares of Stock for which any employee may be granted  Options
under the Plan  pursuant  to  Paragraph  6, (v)  modify the  requirements  as to
eligibility for participation in the Plan, or (vi) with respect to options which
are ISOs,  amend the plan in any respect  which  would cause such  options to no
longer  qualify for ISO  treatment  pursuant to the Internal  Revenue  Code.  No
termination  or  amendment  of  the  Plan  shall,  without  the  consent  of the
individual  Optionee,  adversely  affect  the rights of such  Optionee  under an
Option theretofore granted to him or under such Optionee's Option Agreement.

20. Taxes.  The Corporation may make such provisions as it may deem  appropriate
for the  withholding  of any taxes which it determines is required in connection
with any Options  granted under the Plan. The  Corporation  may further  require
notification  from the Optionees upon any disposition of Stock acquired pursuant
to the exercise of Options granted hereunder.

21. Code References and Definitions.  Whenever reference is made in this Plan to
a section of the Internal  Revenue Code, the reference  shall be to said section
as it is now in force or as it may hereafter be amended by any  amendment  which
is applicable to this Plan. The term  "subsidiary"  shall have the meaning given
to the term  "subsidiary  corporation" by Section 425(f) of the Internal Revenue
Code.  The term "10% Holder"  shall mean any person who, for purposes of Section
422 of the Internal Revenue Code owns more than 10% of the total combined voting
power of all classes of stock of the employer  corporation  or of any subsidiary
corporation.
