Methods and Apparatuses for Calibrating a Sensor
13 Apr 23
A method for determining a calibration function includes: calculating a first distance, between a distribution of target spectra and a comparison distribution of spectra; calibrating the distribution of target spectra with a first preliminary calibration function to form a first distribution of calibrated target spectra; calculating a second distance, between the first distribution of calibrated target spectra and the comparison distribution of spectra; determining that the second distance is less than the first distance; and setting the calibration function equal to the first preliminary calibration function.
