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 1 064 nm WFOV laser receiver. A narrow band interference filter was adopted to realize the noise reduction. A design example of a low noise amplifier suitable to the high-repetition-rate (200 kHz) is given. The design principle of the low noise amplification circuit is introduced. The tested results of receiving FOV angle, dynamic range and receiving sensitivity of the laser receiver with wide FOV are provided.
