Abstract:
1. A light-guide, compact imaging optical system, comprising: an optical device, composed of first and second light-waves transmitting optical elements for converging and collimating light waves, each optical element having at least one light-waves entrance surface, at least one light-waves exit surface and a plurality of external surfaces; at least a first and a second retardation plate carried by the first and the second optical elements on at least a portion of an external surface of each optical element; at least a first and a second polarizing beamsplitter, the first beamsplitter disposed at an angle to at least one of the light-waves entrance or exit surfaces of the first optical element, and the second beamsplitter disposed at an angle to at least one of the light-waves entrance or exit surfaces of the second optical element; and at least one light-waves converging lens covering at least a portion of the first retardation plate and at least one light-waves collimating lens covering at least a portion of the second retardation plate, wherein the exit surface of the first optical element is positioned adjacent to the entrance surface of the second optical element at an interface surface, forming a telescope defining a Fourier plane at the interface surface.
