Abstract
A doppler lidar system includes an acousto-optic modulator. The acousto-optic modulator frequency shifts light to simulate a Doppler effect of a target without moving the target relative to a transceiver. A detector detects a frequency. One or more processors then calibrate the doppler lidar system based on the detected frequency. The acousto-optic modulator is then decoupled to return the doppler lidar system to a normal operating condition. The acousto-optic modulator is coupled in a transmit path or a receive path of the doppler lidar system.
