Abstract
A method for constructing a stereoscopic device is provided. A chassis with front and back openings and that forms a housing framing the front and back openings is constructed. A beam splitter constructed of substantially orthogonally polarizing material faces the back opening and is captively held to the chassis. A single phase shifting optic having a reflective surface coated by a phase shifting film on which the divergent image light is received is placed at an angle non-perpendicular to the divergent image light, such that the phase shifting optic is facing toward the front opening and is substantially parallel to the polarizing material of the beam splitter. The beam splitter and phase shifting optic are in optical alignment with each other within the chassis. A modulator sized to cover at least a portion of the front opening is positioned in front of the front opening.
