摘要
为了解决便携式激光通信视场角测量范围小、要求精度高、测量难度大的问题,采用计算指定通信距离下的链路能量作为视场角测量依据,提出了一种基于便携式激光通信视场角测量的方法和装置,并在此方案设计的高精度测量装置基础上进行了实际试验测量。结果表明,探测器灵敏度为-30dBm时,在1km,2km,3km,4km处测得的激光通信接收视场角分别为1.12mrad,0.94mrad,0.87mrad和0.63mrad。该测试方法和装置能够精确测量便携式激光通信的视场角范围,测试装置可以扩展应用于不同领域的小视场高精度测量。
In order to solve the problems of small measurement range of field of view,high precision and difficult measurement in a portable laser communication,link energy at a specified communication distance was used as the basis for measuring the field of view.A measurement method of field of view based on portable laser communication was proposed.A high-precision measurement device was designed and the actual test and measurement were carried out.The results show that,when detector sensitivity is-30dBm,the receiving field of view of laser communication at1km,2km,3km,4km is1.12mrad,0.94mrad,0.87mrad and0.63mrad respectively.The test method and device can accurately measure the field of view of a portable laser communication.The test device can be extended to high-precision measurement of small field of view in different fields.
