Abstract: The present disclosure is directed to imaging LiDARs with separate transmit (Tx) and receive (Rx) optical antennas fed by different optical waveguides. This pair of optical antennas can be activated at the same time through a dual-channel optical switch network, with the Tx antenna connected to a laser source and the Rx antenna connected to a receiver.
