PROJEKTIONSSYSTEM MIT GERINGEM ASTIGMATISMUS |
摘要 |
<p>LCD projection systems that use reflective LCD imager units commonly use one or more polarization beamsplitters to separate the light incident on the imager from the light reflected by one or more respective imagers. The polarizing beamsplitters introduce astigmatism to the image light from the imagers. According to the present invention, the polarization beamsplitters are adapted to reduce the astigmatism.</p> |
