摘要
目前扫描式激光投影机是利用高速电机带动多个发射镜进行激光光束偏转的,存在着体积大,寿命短,频率不能满足高清视频等要求。根据目前扫描式激光投影机存在的问题,研究设计一种新型的电磁式激光扫描成像器件,它由一对行扫描电磁振荡器和一对场扫描电磁振荡器组成的扫描器件去驱动一片矩形反光镜,对被视频信号调制的激光光束进行偏转,使得反射出的光束通过光学放大镜进行放大后在屏幕上形成视频图像。利用该技术可设计开发一种新型激光电视投影机。
The available scanning laser projector is to drive multiple transmit high-speed motors to implement laser beam deflection, It is bulky, its life is short, and its frequency can not meet the requirements of high-definition video. According to the problems existing in current scanning laser projectors, a new electromagnetic laser scanning imaging device is design. It is composed of a pair of line scanning electromagnetic oscillators and a pair of field scan scanning electromagnetic oscillators to drive a rectangular mirror, by which the laser beam modulated by video signals is deflected. The reflected beam goes through an optical magnifying glass and zooms on the screen to form a video image. A new type of laser television projector can be de- veloped by the aid of this technology.
