| 中文摘要: |
| 随着LCOS技术的发展,投影仪趋于微型化,而投影系统的分辨力也不断提高,因此对投影仪的光源系统的要求就越来越高,希望得到高强度以及光学扩展量小的光束.采用两个LED面光源作为投影仪的照明光源,使用包括了与偏振光转换系统耦合的光棒以及照明透镜的FF光学系统,使光源发出的光得到充分的均匀,并尽量地会聚在LCOS上.模拟结果表明,该照明系统达到了所要求的照度,并且整个系统结构简单,非常紧凑. |

| With the advance in LCOS panel,LCOS projector is the only way to utilize a high resolution and micromation of the projector.Thus we require more intense,focused light with lower extended values.In this paper,we used two panel LEDs and a FF optical system,which includes a polarization conversion system,a light pipe and an illuminating lens.The simulation result shows that the light is uniform on the LCOS and the efficiency is high.The illumination system has a good performance,with also a simple and compact structure. |
