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.

Abstract: In accordance with at least one aspect of this disclosure, a method for seeding an optical beam includes, emitting an optical beam from an energy source towards an optical amplifier along an optical axis, and rotating one or more optical elements disposed with in the beam path of the optical beam between the energy source and the optical amplifier about the optical axis to a align the optical beam with a reference beam.
