摘要： A relay optical system exhibits an action of deflecting light with respect to passing luminous flux as a result of being provided with a light deflection member, and thus a cross-section of the luminous flux can be adjusted to a state of having an appropriate size (enlarged size), that is, a state in which an image is not completely formed but is blurred, at image formation positions of color modulation light valves. Therefore, it is possible to form a favorable image by minimizing moire.
摘要翻译：由于设置有光偏转构件，中继光学系统表现出相对于通过的光束而偏转光的动作，因此可以将光束的横截面调整为具有适当尺寸的状态（放大的大小），即，在色调调节光阀的图像形成位置，图像未完全形成但模糊的状态。因此，可以通过使莫尔条纹最小化来形成良好的图像。

摘要： A projection apparatus includes a light source, a light valve, a light uniforming device, and a lens module. The light source provides an illumination beam. The light valve on a transmission path of the illumination beam converts the illumination beam into an image beam. The light valve has an active surface with a rectangular shape. The light uniforming device is between the light source and the light value. The lens module is between the light uniforming device and the light value. A refractive power of the lens module along a first direction is different from a refractive power of the lens module along a second direction. An f-number of the illumination beam along a direction parallel to a long side of the active surface of the light valve is greater than an f-number thereof along a direction parallel to a short side of the active surface of the light valve.

摘要： Micro-electromechanical display device (“MDD”)-based multimedia projectors (90, 120) of this invention employ an arc lamp (32), a color modulator (42), and anamorphic illumination systems (94, 121) for optimally illuminating a MDD (50, 76) to improve projected image brightness. MDDs employ off-axis illumination wherein incident and reflected light bundles are angularly separated about a hinge axis (78, 110) and the MDD is illuminated by the anamorphic illumination systems of this invention having a slow f/# parallel to the hinge axis and a faster f/# perpendicular to the hinge axis. The resulting anamorphic light bundles (86, 88, 112, 114) illuminate and reflect more light into and off the MDD and through a fast f/# projection lens.

摘要： A method and system for zonal switching for light steering to produce an image having high dynamic range is described. The system comprises: a light source for providing light along an optical path; a spatial light modulator for directing portions of the light to off-state and on-state light paths, thereby producing an image, the spatial light modulator having a plurality of illumination zones corresponding to the image; and a set of sequentially-arranged optical elements in the optical path for steering at least some of the light from a first subset of the plurality of illumination zones to a second subset of the plurality of illumination zones to increase the dynamic range of the image. The dwell time of the one or more sequentially arranged optical elements can be modified to steer light.
