Abstract
A technique for increasing the measurement range of a light detection and ranging (LIDAR) system includes triggering a light source of the LIDAR system to emit light pulses towards an environment at a first repetition rate. A different second repetition rate for operation of a shutter of the LIDAR system is determined. The operation of the shutter is synchronized with the light source, based on the second repetition rate, such that reflections caused by the light pulses arrive at the shutter when the shutter is in different states during the time period. An intensity of the reflections that arrive at the shutter is determined. A range to objects in the environment is determined based on the measured intensity of the reflections.
