提出了一种新型的激光大屏幕显示系统方案使用由计算机控制的三基色全固态激光器作光源,通过分光镜进行混色,由两个振镜分别完成行和帧方向的扫描。并对由振镜扫描引起的枕形失真的原因和纠正方法进行了研究,对系统的控制方法作了简单介绍。 A new type of laser large-screen display system was proposed. The computer controlled three-primary solid-state laser was used as light source. The light was mixed by a dichroic mirror and scanned by two galvanometers respectively. The cause of the pincushion distortion caused by galvanometer scanning and its correction method are also studied. The control method of the system is introduced briefly.
