摘要： A sequential color display system using a white light source (202) to create a full color image projected onto an image plane (214). A dynamic filter (206), typically a series of moving dichroic filters, generates a series of primary colored light beams that are swept across the surface of a spatial light modulator (210). Light rejected by the dynamic filter (206) enters a light recycler (204) and is reapplied to the dynamic filter (206). The light recycler is typically one or more reflective surfaces, including mirrors, baffles, enclosures, lamp reflectors, TIR surfaces, or specially coated material arranged in such a way as to encourage light toward an aperture separating the light recycler (204) and the dynamic filter (206). Typically all three primary colors are produced simultaneously by the dynamic filter (206). The illuminated portion of the dynamic filter (206) is imaged onto the modulator (210) and a controller (216) provides appropriate image data for each portion of the modulator (210) in synchronization with the sweep of the primary color bands across the modulator surface. The primary color bands are modulated by the spatial light modulator (210) and the modulated light is focused by lens (212) onto the image plane (214). The viewer integrates the light arriving at each portion of the image plane (214) over a frame period to provide the perception of a full-color image.

摘要： A method for transmitting light in an image display system includes generating a first cone of light from a first light source. The first cone of light includes a plurality of light beams. A first portion of the first cone is projected in an illumination path. A second portion of the first cone is projected at a surface of a reflector. The second portion of the first cone is reflected to project the second portion of the first cone in the illumination path. The first and second portions of the first cone are received at an entrance of an integrator rod. The second portion of the first cone increases the intensity of light received by the integrator rod.

摘要： An optical system for illumination spatial light modulators. The optical system includes a tall color splitting prism (16) with substantially symmetrical face bonding areas, thereby eliminating the need for external holding plates. The face bonding areas (62) are outside the optically active area. The tall prism (16) allows for better control of stray light, including a heat sink (41) for absorbing stray or OFF state light, preventing overheating of the optical assembly. The tall prism (16) also allows adjustments to be made to any other optical components such as projection lenses and TIR prisms (14).

摘要： Disclosed is an optical component, which comprises a prism element adjacent to a lens element, where the two elements are separated by a small air gap. In disclosed embodiments, the elements have adjacent and parallel surfaces which are substantially planar and which, with the small air gap, operate through Total Internal Reflection (“TIR”) to direct light beams that strike the planar surfaces. Light beams that strike at less than the critical angle are internally reflected, while light beams which strike at greater than the critical angle pass through. The TIR surfaces thereby separate the desired optical signals from the spurious ones. The combined TIR prism lens operates as a single and integrated component which directs desired light beams to a reflective optical processing element such as a Spatial Light Modulator and which focuses the processed light beams as they leave the combined TIR prism lens.
