智能化激光显示系统的设计与研究

研制了一套由激光器,图形输入仪,控制计算机,驱动器,光学工作台及大屏幕等六个部分构成的激光显示系统。理论研究得出,大屏幕所显示图形上的任意点P,均存在一与之对应的振镜偏转角确定值,精确控制振镜的偏转角即可扫描到P点。实验表明,系统可成功实现诸如函数图形、光栅衍射图案、光网光柱及文字动画等多功能智能化激光视频图像的动态输出。

Design and research for an intelligent laser display system

A laser display system consisting of laser, graph input unit, drivers, optical stage and large screen is developed. From theoretical study, we learned that a deflection angle determined by polarization filter corresponds with any point P at the graph displayed on the large screen, and point P can be scanned through accurately controlling deflection angle of the polarization filter. The experiments show that the dynamic output of multi-function intelligent video images such as function graph, grating diffraction patterns, light net, light column, character and cartoon, etc can be performed by the system.
