SYSTEM AND METHOD FOR EMULATING ECHO SIGNALS FOR LIDAR SENSOR

Abstract:

A system is provided for emulating return optical pulses from at least one emulated target in response to a time of flight (TOF) lidar signal. The system includes an optical blocker configured to partially reflect or guide emitted optical pulses emitted by a TOF lidar sensor; a detector configured to detect the partially reflected or guided optical pulses, and to output corresponding electrical pulses; an electrical delay circuit configured to delay the electrical pulses to indicate distance to the at least one emulated target relative to the TOF lidar sensor; at least one laser configured to reemit return optical pulses in response to the delayed electrical pulses; a collimator configured to collimate the return optical pulses; and a diffuser configured to diffuse the collimated return optical pulses over a predetermined range of azimuthal angles toward the TOF lidar sensor.
