基于DPSSL（二极管泵浦固体激光器）的窄脉冲激光引信具有发射脉冲窄、峰值功率高、距离分辨力强的优点，是当前国际上激光引信发展的主要方向。本文以超窄脉冲激光引信为应用背景，介绍了一种主动近距宽视野、窄视场大动态范围探测的光电探测系统，有效提高引信的抗干扰能力。%The laser fuze based on DPSSL （the diode pumped solid state laser） has the advantages of short transmitted pulse and high peak power. It is the main direction of laser fuze. Based on the ultra- short-pulse laser fuze, this paper designs a photoelectricity detection system of active close quarters wide- view and narrow-field to improve fuze＇ s ability of anti-interference.
