【摘要】 在综述了周视激光动态探测技术国内外发展现状的基础上,分析了周视激光动态探测系统目标方位探测原理,并从理论与实际应用两个方面对周视激光探测系统的发射和接收单元进行了全面分析,提出了采用主动探测方式周视激光动态探测系统的设计方案。该系统主要由发射单元、接收单元、信号放大与处理电路组成。探测系统的发射单元由6束扇形线状光束组成,采用分区光束布置方式,实现了周视系统360度全向探测,与之对应的6个光电元件组成接收单元。采用分时轮流工作的方式,6个发射单元实现了分区扫描探测,并完成了驱动电路的设计,最终实现了目标方位的确定和大视场角探测。并提出了一个利用光波导材料实现激光器分区照明探测的方案。更多还原

【Abstract】 Based on the development of panoramic optical system for laser short-range detection, the emission and receiver unit were analyzed from both theory and practical application, and give a design of the detection system. The detection system is active and consists of emission unit, receiver unit, signal amplification and processing circuit. Emission units are made up of six fan-shaped beams, using partition layout and achieving 360°panoramic detection. Receiver units are made up of six photosensitive elements matched with emission units. Focusing on the research that six emission units realize partition scanning detecting by the way of working in time-sharing turn, designing a drive circuit, finally achieving determination of target position and panoramic detecting. Designing a laser partition light detection scheme making use of optical waveguide material.更多还原
