论述了激光告警设备角分辨力的误差源,认为接收电路动态范围不够,光学视场光阑不合适,接收光敏面相对光阑太大,窗口安装误差及在光纤耦合体制下光纤耦合方式不完善都是引起误差的主要原因,文中分别介绍了减少这些误差的方法.

Some factors that lead to angle distinguish error in laser warning device are discussed in this article. For example, dynamic range of the receive circuit is not wide enough, the FOV diaphragm isn't big enough comparing to the photo-sensitive area, mount error for optical window exists and optical fiber coupling method isn't perfect, etc. In this paper, some methods for reducing these errors are introduced.
