摘要： A portion of a nearly spherical reflector is used to direct the electromagnetic radiation onto a small target. The electromagnetic radiation source is displaced from the optical axis of the reflector to maximize flux density at the target with minimal distortion. The present invention is particularly suited to coupling light from an arc lamp into an optic fiber.

摘要： A polarization recovery system includes a polarizing beam splitter transmitting light of a useful polarization in an output direction and reflecting light of a non-useful polarization in a first orthogonal direction substantially orthogonal to the output direction. An initial reflector may reflect the non-useful polarization light in a second orthogonal direction substantially orthogonal to the output direction and the first orthogonal direction, and a final reflector may reflect the non-useful polarization light in the output direction. The non-useful polarization light may be rotated substantially to light of the useful polarization by the initial and final reflectors.

摘要： An illumination system for increasing the brightness of a light source comprises an optical recycling device coupled to the light source, preferably light emitting diode (LED), for spatially and/or angularly recycling light. The optical recycling device spatially recycles a portion of rays of light emitted by the LED back to the light source using a reflector or mirror and/or angularly recycles high angle rays of light and transmits small angle rays of light, thereby increasing the brightness of the light source's output.

摘要： A LCD display backlight system with improved color mixing and efficiency comprises a reflective surface, a plurality of light sources mounted on the reflective surface, a plurality of fractional wave plates and a reflective polarizer. The plurality of fractional wave plates is mounted on spaces between the plurality of light sources on the reflective surface. The reflective polarizer transmits light having a useable polarization and reflects back unused polarization of light onto the reflective surface. A portion of the unused polarization of light reflected from the reflective polarizer passes through a fractional wave plate. The reflective surface reflects the portion of the unused polarization of light through the fractional wave plate such that the polarization of the unused polarization of light is changed to useable polarization, thereby recycling the unused polarization of light into useful light.
