摘要
为减弱背光噪音和大气变化对光通信造成的影响,设计基于虚拟仪器技术的光通信跟踪检测系统,使用虚拟仪器技术开发系统微型组件、软件功能,并对基于中值滤波和重心算法的跟踪检测函数开发支持软件。对系统天线模块中的激光器和调制器进行选型,通过合理的光束散射角度发射出高精度的激光光束。使用虚拟仪器检测模块对激光光束进行检测,控制模块为检测结果进行定位与分配,探测与跟踪模块根据检测结果和激光光束基本信息进行光束对准和跟踪,实现高精度的光通信。实验在多种情况下证明了系统跟踪检测精度高的优点。
To decrease the effects of optical communication from backlit noise and atmosphere, the optical commu- nication tracking detection system was designed based on virtual instrument technology（VIT）. Developing the micro- module and software function of system through VIT, and developing the supporting software of tracking detection func- tion based on median filter and centroid algorithm. Selecting laser and modulator mode in system antenna module, e- mitting laser beam in high precision through reasonable angle, detecting laser beam by virtual instrument detecting module, locating and allocating detecting results by controlling module, aligning and tracking beam according to the detection result and basic information in detection and tracking module. Finally, achieving optical communication in high precision. This method was proved that it has high precision in many conditions.
