  • Publication number: 20170370676
    Abstract: The present disclosure describes a single aperture laser range finder (SALRF). In an implementation, the single aperture laser range finder includes a beam extender including an aperture and an input aperture lens. A matching lens collimates light emitted from an emitter element associated with a single aperture optical circulator and received by the beam extender, respectively. A single aperture optical circulator has an emitter channel associated with the emitter element and a detector channel associated with a detector element. The emitter channel and the detector channel merge together at an input/output aperture. A light gating mechanism is configured to permit received light to enter the detector channel and to prevent the received light from entering the emitter channel. The SALRF has an electronics end cap.
