1. An image processing guide comprising:
- a solid body constructed from a single block of material comprising;
a plurality of surfaces defining an optical pathway from an input surface to an output surface, where said optical pathway connects said plurality of surfaces successively;
wherein said plurality of surfaces comprises at least one curved mirror reflective surface configured to receive light from said optical pathway and to return light to said optical pathway;
wherein said optical signal is not focused to an image plane within the solid body;
wherein said solid body includes a first side which includes a plurality of said surfaces;
wherein said first side has a shape with one geometry and a concavity formed in said shape where said concavity forms one of said surfaces;
wherein said plurality of surfaces comprises a first curved mirror surface on said second side, second curved mirror surface on said concavity on said first side, and a refractive surface on said second side.
