| 摘 要： | 设计了一种针对个人用户使用的微型投影机光学引擎,系统为单片式数字光线处理器结构,采用红绿蓝三色大功率高亮度发光二极管作为光源,使用X棱镜作为合色元件,从而实现38.1～50.8 cm的彩色投影显示.对设计结果进行理论分析后可知,设计结果满足投影显示对颜色的要求,光学引擎的理论效率为16.1%.同时利用Light Tools仿真软件对系统进行建模分析,300万条光线追迹仿真的结果表明,光学引擎的效率为14.6%,与理论分析结果基本符合,屏幕上光通量为22.8 lm,其美国国家标准协会规定的九点照度均匀性达到91.55%和-93.36%,满足设计要求.

| Abstract: | An optical engine of the mini-projector suitable for the personal use is designed. It is a single panel digital light processor (DLP) system by using LED as its illuminator and X prism as its mix-color device, which can provide a 38.1～50.8 cm color projection display. The theoretical analysis shows that the design can satisfy the need of the color projection display with the system efficiency 16.1%. The simulation by using the software is LightTools made. After three million rays are traced, it shows that the efficiency of the optical engine is 14.6% with flux 22.8 lm on the screen. The simulation results coincide with the theoretical analysis of the system efficiency. The ANSI nine-point uniformity of the screen is 91.55%, -93.36%, which can reach the specification of the design. |
