Stereoscopic light recycling device

摘要

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.

1. A stereoscopic device for recapturing light, comprising:
a chassis comprising front and back openings, the back opening open to divergent image light, and forming a housing that frames the front and back openings; a beam splitter constructed of substantially orthogonally polarizing material facing the back opening and captively held to the chassis; a single phase shifting optic comprising a reflective surface coated by a phase shifting film on which the divergent image light is received, placed at an angle non-perpendicular to the divergent image light 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 a modulator sized to cover at least a portion of the front opening and positioned in front of the front opening.
