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.

摘要： Prism elements having TIR surfaces placed in close proximity to the active area of a SLM device to separate unwanted off-state and/or flat-state light from the projection ON-light bundle. The TIR critical angle of these prisms is selected to affect either the off-state light or additionally, any portion of flat-state light reflected from the SLM. These TIR surfaces are placed to immediately reflect the unwanted light as it comes off the SLM, thereby preventing the contamination of light along the projection path, which tends to degrade the system contrast. To further improve the optical performance of the system, these TIR prisms can be attached directly to the SLM package, completely eliminating the package window. Also, these TIR prism can be coupled to DMDs having asymmetric mirrors, which tilt through a larger angle for the ON-light to provide high etendue and lumen output, but through near-zero degrees for the OFF-light, thereby improving the separation of any unwanted light from the off/flat states.

摘要： A sequential color display system using a white light source to create a full color image projected onto an image plane. A dynamic filter, 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. Typically all three primary colors are produced simultaneously by the dynamic filter. The illuminated portion of the dynamic filter is imaged onto the modulator and controller provides appropriate image data for each portion of the modulator 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 and the modulated light is focused by lens onto the image plane. The viewer integrates the light arriving at each portion of the image plane over a frame period to provide the perception of a full-color image.

摘要： The present application describes embodiments of a neutral density color wheel filter. According to one embodiment, a neutral density color wheel (100) includes an opaque coating (135) over one or more color segments (120, 130, 140, 150, 160, 170) with randomly placed transmissive regions (131). The transmissive regions (131) can be configured to substantially transmit incident light and the opaque coating (135) can be configured to substantially block or absorb the incident light. Alternatively, the transmissive regions (131) can be configured to substantially transmit the incident light. The color segments with opaque coating (135) and transmissive regions (131) substantially eliminate light recycling due to the reflection from the color wheel. The light transmission from the color wheel (100) is independent of the optics of a display system.
