摘要： A stereoscopic light recycling device is provided. A beam splitter is constructed of substantially orthogonally polarizing material on which divergent image light is received and is positioned at an angle to a source of the divergent image light. A phase shifting optic includes a reflective surface coated by a phase shifting film and is positioned at an angle non-perpendicular to at least a portion of the image light from the beam splitter. The angle of the phase shifting optic is dependent on the angle of the beam splitter.

摘要： Systems and methods provide a retro-reflective screen covered with a screen material. The retro-reflective screen has a plurality of retro-reflective screen elements positioned within the screen material. At least one of the plurality of retro-reflective screen elements is oriented so as to have an incident angle that is less than 45 degrees. Additionally, a portion of the screen material that corresponds to the at least one screen element has an incident angle that is greater than the incident angle of the at least one screen element. Additionally, the system also comprises at least one projector that (i) generates light characterizing an image or video and (ii) projects the light onto the retro-reflective screen.

摘要： The PCS may include a polarizing beam splitter, a polarization rotating element, a reflecting element, and a polarization switch. Typically, a projector outputs randomly-polarized light. This light is input to the PCS, in which the PCS separates p-polarized light and s-polarized light at the polarizing beam splitter. P-polarized light is directed toward the polarization switch on a first path. The s-polarized light is passed on a second path through the polarization rotating element (e.g., a half-wave plate), thereby transforming it to p-polarized light. A reflecting element directs the transformed polarized light (now p-polarized) along the second path toward the polarization switch. The first and second light paths are ultimately directed toward a projection screen to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.

摘要： A light-source module includes a light-source unit, a first projection lens, a first lens, a mirror wheel, a first light-guiding unit, a second light-guiding unit, and a second projection lens. The first projection lens has an entrance pupil. The light beam provided by the light-source unit can pass through the first projection lens via the entrance pupil and then is guided to the mirror wheel. With the rotation of the mirror wheel, when the light beam passes through the mirror wheel, it becomes a transmission light beam. At different time, when the light beam is reflected by the mirror wheel, it becomes a reflection light beam. The second projection lens has a first exit pupil and a second exit pupil, in which the transmission light beam and the reflection light beam pass through the second projection lens via the first exit pupil and the second exit pupil, respectively.
