Abstract
A light detection and ranging (LIDAR) device that may be included in an autonomous vehicle includes a transmit optical coupler, a first receive optical coupler, and a second receive optical coupler. The transmit optical coupler is positioned between the first and second receive optical couplers to enable the receive optical couplers to receive a return beam that may be directed (by a mirror) to either side of the transmit optical coupler. The first and second receive optical couplers may include dual-polarization optical couplers and may each be coupled to two coherent receivers to support dual-polarization return beam reception.
