Abstract
A stereoscopic device for recapturing light is provided. A chassis is open on front and back sides and forms a rectangular housing with top, bottom, and two sides that frame the front and back openings. A polarizing beam splitter is angled away from the back opening of the chassis and captively held by the chassis. The beam splitter is constructed of substantially orthogonally polarizing material. A phase shifting optic having a reflective surface coated by a phase shifting film is angled toward the front opening, wherein the beam splitter and phase shifting optic are in optical alignment with each other within the chassis. A modulator sized to cover the front opening is positioned in front of the chassis.
