A FMCW LIDAR system for simultaneous beam scanning of the target environment. The system can include a photonics assembly couplable to a beam steering module. The photonics assembly is configured to receive a frequency modulated laser beam and can include an optical splitter and a coherent receiver. The optical splitter can be configured to optically split the frequency modulated laser beam into a local laser beam and a target laser beam, deliver the target laser beam to the beam steering module, and receive the target laser beam reflected by a target from the beam steering module. The coherent receiver can be configured to mix the local laser beam and the target laser beam to produce an output signal.

LIDAR system based on multi-channel laser module for simultaneous beam scanning of target environment

A LIDAR system and method for determining a distance and a velocity of a target. The LIDAR system can include laser bank () is configured to generate a laser field from a first laser beam having a positive frequency sweep and a second laser beam having a negative frequency sweep, an optical combiner (), an optical coupler (), a photoreceiver (), and a control circuit (). The optical coupler direct a first portion of the laser field at the target such that the first portion is reflected by the target to the optical combiner. The optical combiner can optically combine the portions of the laser field. The output an 1-output () and a Q-output () according to the optically combined portions of the laser field. The control circuit can determine a nominal beat frequency, which corresponds to the distance of the target, and a frequency shift, which corresponds to the velocity of the target, accordingly.

A LIDAR system and method for determining a distance and a velocity of a target. The LIDAR system can include a laser modulated by a laser modulator, an optical combiner, an optical splitter, a photoreceiver, and a control circuit. The optical splitter can optically split the modulated laser beam into a first laser beam and a second laser beam and direct the first laser beam at the target such that the first laser beam is reflected by the target to the optical combiner. The optical combiner can optically combine the first laser beam and the second laser beam. The output an I-output and a Q-output according to the optically combined first laser beam and second laser beam. The control circuit can determine a nominal beat frequency, which corresponds to the distance of the target, and a frequency shift, which corresponds to the velocity of the target, accordingly.
