Optical devices particularly for remote viewing applications
First Claim
1. An optical device for transferring light within a given field-of-view, comprising:
- an input aperture;
reflecting surfaces, andan output aperture located in spaced-apart relationship from said input aperture such that light waves, located within the said field-of-view, that enter the optical device through said input aperture, exit the optical device through said output aperture, andcharacterized in that said reflecting surfaces are at least one pair of parallel reflecting surfaces and that part of said light waves located within said field-of-view that enter the input aperture, pass directly in free space to the output aperture without being reflected, while another part of the light waves within said field-of-view that enters the input aperture, arrives at the output aperture after being twice reflected by said at least one pair of parallel reflecting surfaces.

Abstract
There is provided an optical device for transferring light within a given field-of-view, comprising an input aperture; reflecting surfaces, and an output aperture located in spaced-apart relationship from the input aperture such that light waves, located within the field-of-view, that enter the optical device through the input aperture, exit the optical device through the output aperture, wherein the reflecting surfaces are at least one pair of parallel reflecting surfaces and that part of the light waves located within the field-of-view that enter the input aperture, pass directly to the output aperture without being reflected off the at least one pair of parallel reflecting surfaces, while another part of the light waves within the field-of-view that enters the input aperture, arrives at the output aperture after being twice reflected by the at least one pair of parallel reflecting surfaces.
