摘　　要：受常规弹药空间及功耗限制,无法采用多个激光接收器实现大视场探测,且系统结构应简单易实现,故传统的四种大视场光束布局方式无法直接应用.为此,本文设计了一种新型的光学大视场旋转扫描接收方案,根据激光引信光学接收系统结构特点,应用Zemax光学软件,在非球面光学设计理论基础上,设计出多级光学聚焦整形接收透镜组.仿真结果显示相对于传统单级聚焦透镜,多级接收透镜组将光斑中心辐照亮度提高了近8倍,使光斑能量集中,尺寸减小.加工了非球面透镜组并进行了实验.结果表明该接收光学系统可有效汇聚激光回波能量,提高系统探测距离,实现目标周向360°大视场探测.As the limit of fuze space in conventional ammunition, it is impossible to arrange a number of laser receivers. Meanwhile, the system structure should be as simple as possible, so the traditional beam layout cannot be directly applied. Therefore, a new receiving system utilizing the technology of optical large field rotary scanning was proposed. Based on the optical structure of laser fuze and the aspherical optical design theory, a set of multi-level optical focusing plastic lens were devised by using the application software called Zemax. Compared with the traditional single-stage focusing lens, the brightness of center irradiation was enhanced by nearly 8 times, the size of spot was decreased and the energy was centralized, which were shown by the simulation results. Then, a set of aspherical lens were developed as well as the related experiments. The results show that the echo energy of pulsed laser can be effectively converged and the detection range can be enhanced in the system described above. Finally, the large field detection whose circumferential view angle of the target is 360° is well realized.
