新型激光显示扫描系统设计

阐述了一种新型激光显示扫描系统的设计。根据光线反射定律，提出了采用多面转镜和二次反射面相互配合来实现光束在屏上线性扫描的系统模型。利用该模型，可以避免使用传统激光电视中的高速转镜装置，有较强的现实意义。在此基础上，提出了2种实现方案，对其分别建立了模型，并进行了模拟，计算了屏上光点位置、束斑大小、进行了数据分析，最终确定等边转镜和不规则二次反射面的配合，是一种实现扫描显示的方案。

Novel scan system of laser display

The design and principle of a novel scan system of laser television are described. Based on the law of reflection,using the rotation polygonal mirror and the second reflection mirror, the linear scanning of laser beam is realized by the novel scan system. In this system, the high speed polygonal mirror can be avoided, which is good for reduction of cost. Two projects are submitted. By simulation, the position and the shape of facula on the screen are achieved. After comparing and analyzing, it is confirmed that the cooperation of equilateral rotating mirror and special reflection mirror is a project with high feasibility, which can realize the scan display effectively.
