Most of the current lasser television designs employ polygonal mirrors for horizontal linesand a galvanometer for vertical lines. The video signals directly control the operation of the line and frame scanning. This conventional control mode posed over harsh requirements for the angular division accuracy and the stability of the rotating speed. In this paper a new control scheme is presented to overcome the existing problems. A memory buffer is inserted between the video output and the optical modulator. The operational principle of the buffer is as follows. The video signals are initially stored in the frame form. Each storage unit in the memory and each pixel on the screen are one - to - one correspondence. The orientations of the line mirror and the frame mirror simultaneously determine both the position of the beam on the screen and the storage address of the corresponding pixel in the memory. The real - out digital signal is D/A converted into image signal and then fed to an intensity modulator. In this scheme the effects of the polygo- nal angular division error and the fluctuation of the rotating speed on the image quality are negligi- ble.

目前多数激光电视采用的控制方式对多面转镜的角度分割精度和转速的稳定性要求过分苛刻,制作难度极大。本文提出了一种新的控制方案:在视频输出和光调制器间设置内存缓冲,将视频信号以帧形式存储,存储器的每个单元与屏幕上的像素是对应的关系,扫描头的转镜和摆镜方位也确定了该位置像素数据在存储单元的地址。电子单元将该地址的存储单元数据信号读经D/A换为电压信号,送至光调制器调制光强。采用这种茶方式,极大降低了光学扫描系统的制作难度。
