Efficient Laser Illumination for Scanned Lidar
20 Jul 23
Lidar transmission optics and systems project more laser pulse energy per pixel instantaneous field-of-view (IFOV) to a portion of a sensor field of view (FOV), e.g., a portion that would be expected to have both close and distant objects of interest, and proportionally less pulse energy per pixel IFOV to other portions of the sensor FOV, e.g., those that would be expected to have or see only close objects of interest.
