Abstract: One example method involves repeatedly scanning a range of angles in a field-of-view (FOV) of a light detection and ranging (LIDAR) device. The method also involves detecting a plurality of light pulses intercepted for each scan of the range of angles. The method also involves comparing a first scan of the range of angles with a second scan subsequent to the first scan. The method also involves detecting onset of a saturation recovery period of the light detector during the first scan or the second scan based on the comparison.
