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. The Tx and Rx antennas can be positioned adjacent to each other, so they point to approximately the same far-field angle. No optical alignment between the Tx and Rx is necessary. This LiDAR configuration, referred to herein as pseudo-monostatic LiDAR, eliminates spurious reflections and increases the dynamic range of the LiDAR.
