ABSTRACT:
Apparatus for combining information beams by using a space variant mirror in the context of free space optical switching and computing, where light beams comprise beamlets that are focused onto surfaces to form arrays of light spots. Beam combining is achieved by positioning the space variant mirror to coincide with the plane on which the spots are focused, and to thereby allow one beam to pass through the space variant mirror without loss and another beam to be reflected off the space variant mirror, also without loss.
