Abstract: Image projectors with increased light intensity and methods for providing brighter images are provided. Image projectors, described herein, can provide the brightness while still providing any or all of compactness, low power consumption, and long lifetime. To increase brightness, sectional mirrors are used to respectively compress the light from two light sources into a single pupil (e.g. an aperture) of an imaging device. The compression can be accomplished by regions (e.g. sections) of the mirror having different angles with respect to the pupil. Relatively little light may be lost in the compression since minima for a light intensity pattern from a light source may occur between the regions that reflect the light.

Abstract: A multi-lamp arrangement for optical systems includes plural lamps and a collective light guide, where each lamp is positioned such as to transmit light into respective light guides that are both optically connected to the collective light guide. In one embodiment, one of the lamps is optically connected to the collective light guide by a mirror and-prism arrangement and an intermediate light guide and an intermediate mirror-and-prism arrangement. An augmented color modulator may be provided with a number of color fields, where the number of identical color fields is equal to the number of lamps.

Abstract: A multi-lamp arrangement for optical systems comprising two lamps or more (10, 15) and a collective light guide (58), where each lamp is positioned such as to transmit light (20) into respective light guides (36, 46) that are both optically connected to the collective light guide (58). In one embodiment, one of the lamps is optically connected to the collective light guide by means of a mirror (38)-and-prism (40) arrangement and an intermediate light guide (30) and an intermediate mirror (32)-and-prism (34) arrangement. The invention also comprises an augmented color modulator (62) with a number of color fields, where the number of identical color fields are equal to the number of lamps. The invented multi-lamp system will produce a flux level that is equal to or better than known systems but with fewer lamps, thus yielding reduced material cost, manufaturing cost and operating costs, reduced power consumption and reduced product temeperature.

Abstract: A projection system configured to project a stereographic image onto a viewing surface is provided. The projection system includes a light source configured to produce a beam of light, a beam splitter configured to split the beam of light into a right image beam and a left image beam, an image engine configured to produce the stereographic image, and a projection lens configured to project a left-eye image and a right-eye image onto the viewing surface. The image engine includes a left optical path configured to produce the left-eye image from the left image beam, the left optical path including an upstream left polarizer, a left image-producing element and a downstream left polarizer, and a right optical path configured to produce the right-eye image from the right image beam, the right optical path including an upstream right polarizer, a right image-producing element and a downstream right polarizer.
