摘要
介绍了一种用于两个光学平台之间光轴自动对准和稳定光束的设计方案。以可绕ｘ，ｙ，ｚ三个方向转动的导光管为单元，组成导光臂连接两个光学平台，消除两个平台之间相对运动产生的光轴对接偏差。用压电陶瓷驱动的倾斜镜作光束稳定元件，消除光束自身的漂移和平台间高频振动产生的光轴偏差。
A system for automatically aligning and stabilizing a high energy laser beam is designed. The optical train of high energy laser system is usually set up on different platforms, but optical elements in the train must be coaxial. A guiding light arm is designed to align the laser beam propagating between platforms. A unit of the arm is like a periscope. The guiding light arm in good condition can make the output direction of the laser beam relative to the final platform unchange when platforms move at a low frequency. A device for stabilizing high energy laser beam, including a null position sensor, a tilting mirror and its servo electronics device, a beam splitter and a lens, is used to compensate for the drafting of laser beam in real time. The design combines the guiding light arm with the device for stabilizing laser beam. A small system is made and the accuracy of aligning and stabilizing a He-Ne laser beam is less than 5μrad.
