Abstract:
1. A system for a beam transmitting and receiving instrument comprising: a beam emitting device for producing an emitted beam along a first path; a beam redirecting device for intercepting said emitted beam along said first path and producing a redirected beam for direction through a transmission aperture toward a target along a second path; a first at least partially reflective surface disposed at an angle transversely along said first path; a second at least partially reflective surface disposed proximately to said first at least partially reflective surface, such that a visual image of said target is presented at a visual aperture of said instrument along a visual path substantially comprising said second path and said first path to said first and second at least partially reflective surfaces to said visual aperture; and a light emitting display viewable through said second at least partially reflective surface, and wherein said second at least partially reflective surface comprises a dichroic mirror for allowing light produced by said light emitting display to at least partially pass through from said light emitting display to said visual aperture.
