Patent ID: 8384999

Claim:
An optical apparatus comprising a curved embedded ridged reflector module, wherein said module comprises an optical substrate and optical superstrate having inter-engaging ridged surfaces with a freeform profile, wherein the interengaging ridged surfaces comprise alternating first surfaces and second surfaces and wherein at least said first surfaces are freeform curved; a reflective layer formed on at least one of said surfaces; said reflective layer being partially reflective and partially transmissive; and a complementary lens configured to receive a projected image, from a projector, and directs output rays from the projector onto the ridged surfaces on a first side of said module, wherein said module and said complimentary lens are arranged in an off axis optical configuration and wherein said complimentary lens is freeformed to pre-compensate for optical aberrations and distortions resulting from the embedded ridge reflector module such that in use, an augmented image, comprising reflected rays from the projector and transmitted rays from an object located on a second side of the module, is correctly presented to a viewer located on a first side of the module without further conditioning of the reflected rays.
