Claim:
1. A method for constructing a stereoscopic device for recapturing light, comprising: constructing a chassis comprising front and back openings, the back opening open to divergent image light, and that forms a housing that frames the front and back openings; facing a beam splitter constructed of substantially orthogonally polarizing material to the back opening, wherein the beam splitter is captively held to the chassis; placing at an angle non-perpendicular to the divergent image light a single phase shifting optic comprising a reflective surface coated by a phase shifting film on which the divergent image light is received, such that the phase shifting optic is facing toward the front opening and substantially parallel to the polarizing material of the beam splitter, wherein the beam splitter and phase shifting optic are in optical alignment with each other within the chassis; and positioning in front of the front opening a modulator sized to cover at least a portion of the front opening.
