摘要： An improved optical baffling device for use with an optical projection system has a base; a plurality of flat reflective surfaces of an equal size on a corresponding member of reflectors mounted on the base, the reflective surfaces being substantially parallel to each other; and the corresponding number of slits disposed in an alternating relationship with the reflective surfaces. A fraction of light from a light source is focused on each of the reflective surfaces and transmitted to a projection screen through a corresponding slit of the optical baffling device. Sine a fraction of light is processed separately, it becomes possible to enhance the optical efficiency of the optical projection system with a reduced amount of modulation of the optical path.

摘要： An optical projection system, displaying an image of pixels on a projection screen, includes a light source for generating a white light beam, wherein the white light beam has a first, a second and a third primary light components, each of the primary light components being one of the primary colors, a pixel filter for filtering the white light beam into each of the primary light beams of each of the primary light components, wherein the pixel filter made of a set of R, G, B color sections, and an array of M.times.N actuated mirrors provided with an active matrix, M and N being positive integers, respectively, each of the actuated mirrors being capable of reflecting the white light beam from the light source to any one of the color sections and modulating an intensity of the light beam passing through the pixel filter in response to an electric signal applied to the active matrix. In the system, the electric signal includes a plurality of time interval corresponding to a pixel driving time, wherein each time interval is divided into three time slots to be allocated to the color sections, respectively.
摘要翻译：在投影屏幕上显示像素的图像的光学投影系统包括用于产生白色光束的光源，其中白色光束具有第一，第二和第三原色光分量，每个初级光分量作为原色之一，用于将白光束过滤到每个初级光分量的每个主光束中的像素滤光器，其中由一组R，G，B彩色部分和阵列的MxN致动反射镜分别设置有有源矩阵，M和N分别为正整数，每个致动反射镜能够将来自光源的白光束反射到任何一个颜色部分，并且调制响应于施加到有源矩阵的电信号，光束通过像素滤波器。在系统中，电信号包括对应于像素驱动时间的多个时间间隔，其中每个时间间隔被分成三个时隙以分配给颜色部分。
