  • Multiplexer for laser ranging devices and the like
    Patent number: 5883706
    Abstract: A multiplexer for laser range finders and the like has a plurality of laser transmitters disposed about the periphery thereof. Each of the laser transmitters transmits a beam which is substantially smaller than the return beam received by the laser receiver. The laser receiver and each of the laser transmitters are configured to have a substantially common optical axis such that laser beams transmitted by the laser transmitters substantially overlap at a plane of interest so as to provide enhanced illumination thereby.
