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.
摘要翻译：一种使用白色光源产生投影到图像平面上的全色图像的顺序彩色显示系统。动态滤波器（通常是一系列运动的二向色滤波器）产生一系列沿着空间光调制器的表面扫过的主要有色光束。通常所有三原色都是通过动态滤波器同时产生的。动态滤波器的照明部分被成像到调制器上，并且控制器为跨越调制器表面的原色带的扫描同步地为调制器的每个部分提供适当的图像数据。主色调由空间光调制器调制，并且调制的光被透镜聚焦到图像平面上。观看者在帧周期上集成了到达图像平面每一部分的光以提供全色图像的感知。

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.

摘要： A three element prism system and method for splitting/combining three different colors of light arranged such that the size of a selected one of the color prism, such as for example, the red prism and, consequently the clear aperture, are increased without a corresponding increase in the size of the other prisms (e.g., the blue and green prisms). This is accomplished by adjusting the air gap A2 of the selected light path (e.g., red) so that the effective total selected light path T, which includes the selected light air gap A2 and the selected light glass path G2 is the same as the total path length T of both the other light paths (e.g., green and blue) comprised of air gap A1 plus glass path G1.

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 limit 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.

摘要： A method for compensating for a shift in color in a light source and a system of color illumination for a projection visual display (PVD) system. In one embodiment, the method includes: (1) field sequentially operating an array of emitters to generate a sequence of light beams, each light beam comprising an uncompensated saturated color, (2) determining a compensated target color from the uncompensated standard color, the compensated target color determined based upon a variation in the uncompensated standard color and variations in at least two other uncompensated standard colors, (3) combining a first light beam of a first color with a second light beam of a second color to produce said compensated target color, the first and second light beams combined in an optical path to travel concurrently, the combination of the first and second light beams resulting in a composite color coordinate and without exceeding the etendue limit and (4) directing the combination of the first and second light beams at the spatial light modulator, said modulator operable to receive the combination and produce a desired color on a display.

摘要： Prism elements having TIR surfaces placed in close proximity to the active area of a SLM device 302 to separate unwanted off-state 324 and/or flat-state 326 light from the projection ON-light bundle 322. 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 300, 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.
摘要翻译：具有TIR表面的棱镜元件靠近SLM装置302的有源区域放置，以将不想要的截止状态324和/或平坦状态326与投影ON-light束322分离。这些棱镜的TIR临界角为被选择以影响关闭状态光或另外，从SLM反射的平面状态光的任何部分。这些TIR表面被放置成在脱离SLM时立即反射不需要的光，从而防止沿着投影路径的光的污染，这倾向于降低系统对比度。为了进一步提高系统的光学性能，这些TIR棱镜可以直接连接到SLM封装300，完全消除了封装窗口。此外，这些TIR棱镜可以耦合到具有不对称反射镜的DMD，其通过较大的角度倾斜以使ON-light提供高的光通量和流明输出，但是对于OFF光而言接近零度，从而改善来自关闭/平坦状态的任何不需要的光。
