| 摘 要： | 在目标跟踪系统中,由于大气湍流的影响导致光波振幅和相位的起伏.为了能够精确地跟踪目标,首先必须消除大气湍流造成的光斑抖动.文中主要介绍了一种基于压电陶瓷(PZT)的激光大气传输倾斜校正系统,系统由两部分组成:探测系统和校正系统.探测系统使用可以直接探测光斑重心位置的位敏传感器(PSD);校正系统使用压电陶瓷驱动的高速倾...

| Abstract: | In object tracking system,the amplitude and phase of the beacon light is fluctuated which is caused by the atmosphere turbulence.In order to track the target accurately,the facular vibration made by the atmosphere turbulence should be avoided.In this paper,the tilt correction system for laser atmospheric propagation based on PZT was introduced.The system was composed of detection and correction system.The position sensitive device(PSD) which could directly get the centroid of facular was used as the detecto... |
