本文叙述伺服控制动圈式和动铁式振镜的主要性能。它们的重复精度分别是优于±0.2%和±0.3%。阶跃上升时间分别是1.5毫秒和1.2毫秒。位置分辨角小于12弧秒,可为激光光路提供准确而迅速的偏转扫描。已在激光光阀大屏幕显示中得到应用。
This article describes the main features of servo-controlled moving coil and moving galvanometer. Their repeatability is better than ± 0.2% and ± 0.3%, respectively. Step rise time is 1.5 milliseconds and 1.2 milliseconds respectively. Position resolving angle of less than 12 arc seconds, the laser light path to provide accurate and rapid deflection scan. Has been in the application of laser light valve large screen display.
