数学公式

The design principle of the laser receiver with wide FOV for the laser command guidance and laser-beam riding guidance is introduced. A mathematic model of receiving light field is presented. The formula for the viewing angle of the detecting optical system was derived according to the diffraction light field of the oblique incidence parallel light. Taking a detecting optical system with the collecting objective for example, the design characteristic that the receiving optical system needs not only an extra large relative aperture but also an unvignetting receiving performance is discussed on the premise of meeting the requirement of 1064nm WFOV laser receiver.

介绍激光指令制导和激光驾束制导的大视场激光接收机的设计原理，给出接收光场的数学模型，由斜入射平行光的衍射光场推出探测光学系统的视场角公式，根据1064nm大视场激光接收机技术要求，以聚光物镜型探测光学系统为例，探讨接收光学系统既须具备特大相对孔径，又须具备无晕接收性能的设计特点，采用窄带干涉滤光镜进行光学滤波降噪。
