ABSTRACT:
Apparatus which directs light rays from a distant target area scene to a plurality of wavelength detection systems without wavelength degradation. A reflective afocal telescope directs the light rays from the scene to a MEMS mirror array which redirects the rays to selected ones of the detection systems. The MEMS mirror array has individually controllable mirror elements which are driven to predetermined angular orientations to accomplish the light ray redirection. Outputs from the detection systems may be provide to a computer for analysis and/or viewing.
