ABSTRACT:
A single aperture opto-mechanical system for transmitting two small-aperture laser beams and single received laser beam. The two pencil-thin transmitted beams are co-aligned within 150 micro-radians in the same direction but have optical axes that are displaced laterally. An in-coming beam is received along a path that is essentially parallel with the path of the transmitted beams within 500 micro-radians. The small-aperture transmitted beams each pass through a hole in a metal mirror beamsplitter that is positioned to reflect the received light energy at a 90 E angle through a narrow band-pass filter and focused by an aspheric glass lens that directs the received beam energy onto a receiver detector. The beamsplitter has indexing features that provide self-alignment of the beamsplitter to the laser mount.
