Abstract
A method of detecting optical crosstalk in a LIDAR system includes selectively activating and deactivating light sources of a light source array; triggering a measurement of the field of view (FOV) during which at least one targeted region of the FOV is illuminated by the light source array and at least one non-targeted region of the FOV is not illuminated by the light source array; generating electrical signals based on at least one reflected light beam being received by a photodetector array, where the photodetector array comprises a targeted pixel group corresponding to the at least one targeted region of the FOV and a non-targeted pixel group corresponding to the at least one non-targeted region of the FOV; and detecting optical crosstalk that appears at at least one portion of the non-targeted pixel group based on electrical signals from the targeted pixel group and the non-targeted pixel group.
