Thin microprojector with switched beam bender and method of operating the same
Abstract:
A video projector includes a reduced size spatial light modulator (400) that spatially modulates light from a light source (502) according to only a portion (e.g., ½) of a video frame at a time. A beam steerer (508, 600, 1600) steers spatially modulated light from the spatial light modulator to a correspond region (e.g., upper half, lower half) of a projection screen/surface (512) and one or more lenses (506, 510, 702, 802, 1002, 1008, 1100, 1300, 1502) insure that the spatially light modulator (400) is imaged onto the projection screen/surface (512).
Abstract(Chinese):

视频投影仪包括缩小尺寸的空间光调制器（400），其仅仅根据视频帧的一部分（例如，1/2）来空间调制来自光源（502）的光。 光束操纵器（508,600,1600）将来自空间光调制器的空间调制光转向投影屏/表面（512）和一个或多个透镜（506,510）的对应区域（例如，上半部分，下半部分） ，702，802，1002，1008，1100，1300，1502）确保空间光调制器（400）被成像到投影屏/表面（512）上。
