ABSTRACT:
The laser range finding system includes a light detection and ranging (LIDAR) sensor unit (SU) and a LIDAR processor unit (PU). The LIDAR SU is for transmitting light pulses and receiving resulting input light signals reflected from objects within the field of view of the SU. The LIDAR SU includes a flash LIDAR illuminating laser source for transmitting light pulses. The LIDAR illuminating laser source includes an illuminating laser and zoom optics operatively associated with the laser. A LIDAR receiver receives resulting input light signals reflected from the objects. The LIDAR receiver includes a sensor; and, a flash readout integrated circuit (IC). The flash readout IC measures the transit time of the light pulses. The LIDAR processor unit (PU) is operatively associated with the LIDAR SU and it utilizes flash LIDAR ranging. A power source is operatively coupled to the LIDAR PU. Zooming of the transmitted light pulses results in the received resulting input light signals illuminating a relatively reduced area of the frame. Thus, a flash LIDAR image of relatively reduced resolution but enhanced range is provided by utilization of the transit time measurements.
