Abstract: A novel projection system includes a base signal source, a highlight signal source, a base/highlight destination, and a shared optical element. A base signal provided by the base source and a highlight signal provided by the highlight source are combined by the shared optical element. In a particular embodiment, the base signal source and the highlight signal source each include a light source, a spatial light modulator, and optics, and the base/highlight destination includes optics and a spatial light modulator. In a more particular embodiment, the base signal source and the highlight source provide spatially modulated lightfields to the shared optical element. In another particular embodiment, the base signal and the highlight signal are modulated by the spatial light modulator of the base/highlight destination after being combined.

Abstract: A projection system and calibration method therefor relate to a light source configured to emit a light in response to an image data, an illumination optical system configured to steer the light, the illumination optical system including a first mirror and a second mirror, a digital micromirror device (DMD) including a plurality of micromirrors respectively configured to reflect the steered light to a filter as on-state light or to reflect the steered light as off-state light to a light dump; determining a deviation between an actual angle of orientation and an expected angle of orientation of the DMD; calculating a first amount of angle adjustment corresponding to the first mirror and a second amount of angle adjustment corresponding to the second mirror; and actuating the first mirror according to the first amount and the second mirror according to the second amount.

Abstract: One or more perforation hole pattern methods are applied (402) to generate a spatial distribution of perforation holes forming a semi-random pattern for an image display screen. The image display screen is perforated (404) with the spatial distribution of perforation holes forming the semi-random pattern. Image rendering light is emitted (406) with a light projector toward the image display screen that is installed in an image rendering environment. At least a portion of the image rendering light emitted from the light projector is reflected (408) by the image display screen, toward a viewer.

Abstract: A method for mitigating modal noise includes applying a time-varying mechanical force to a fiber segment of the multimode optical fiber in at least a first direction orthogonal to a fiber axis of the multimode optical fiber within the fiber segment. A modal-noise mitigator for a multimode optical fiber includes an actuator configured to apply a time-varying mechanical force to a fiber segment of the multimode optical fiber in at least a first direction orthogonal to a fiber axis of the multimode optical fiber within the fiber segment.

Abstract: Three dimensional (3D) glasses suited for wearers with varying facial geometries may include a frame adapted to position spectrally filtering lenses at a particular distance from the eyes of the wearer. The 3D glasses may include a means for adjusting the distance between the lenses and the eyes of the wearer. The lenses may include positive runout.

Abstract: A projector system comprising a laser light source, a collimating lens, a fly-eye lens, an integrating rod and a first modulator is disclosed. The light from a laser light source/fiber illuminates a collimator to substantially collimate the light and then is transmitted through a fly's-eye lens. The fly's-eye lens provides a desired angular/spatial light distribution for further processing to a first modulator of the projector system.

Abstract: A novel light source for a 3D display system includes a plurality of left eye light emitters and a plurality of right eye light emitters. The left eye emitters include a broad spectral distribution emitter and an overlapping narrow spectral distribution emitter in each of the blue, green, and red color bands. Similarly, the right eye emitters include a broad spectral distribution emitter and an overlapping narrow spectral distribution emitter in each of the blue, green, and red color bands. The combined spectral distributions of each of the broad and narrow emitters provide a primary light for each color and for each eye that has a desirable spectral shape, including wide bandwidth and short tail(s). The invention thus minimizes cross-talk and speckling in left- and right-eye images of 3D display systems.
