Abstract: A remote sensing device may include a mobile platform, and a LIDAR transceiver carried by the mobile platform. The LIDAR transceiver may include an optical source, a detector, and a duplex optical element coupled downstream from the optical source and upstream from the detector. The duplex optical element may have an optical flat, and a reflective layer on the optical flat. The reflective layer may be spaced apart from peripheral edges of the optical flat. The duplex optical element may be configured to reflect an output of the optical source via the reflective layer and directly to a target, and the duplex optical element may also be configured to pass through a return optical signal reflected from the target to the detector. The return optical signal may pass through the optical flat between the peripheral edges and the reflective layer.

The LIDAR transceiver may further include an optical source, a detector, and a duplex optical element coupled downstream from the optical source and upstream from the detector. The duplex optical element may be configured to direct an output of the optical source to a target, and direct a return optical signal reflected from the target to the detector.
