| 摘 要： | 利用晶体的电光效应设计了一种可以取代像增强器曝光闸门作用的电光开关系统，阐明了晶体电光效应的原理及电光开关取代像增强器的必要性与可行性，借助光学软件Zemax仿真得到了光开关的光路系统以及开关通断时的光斑图样，此仿真结果以及静态实验结果都表明,晶体光开关可应用于激光雷达光路中，且曝光时间可达ns量级，从而摆脱对像增强器的依赖。 |
| 关 键 词： | 光开关 激光雷达 像增强器 曝光时间 |

| Abstract: | A crystal electro-optical switch which can substitute the image intensifier’s shutter was designed using the electro-optical effect of crystal. The principle of the electro-optical effect and the necessity and feasibility of the electro-optical switch was illustrated. Optical path system of the switch and the spot figure of switch on/off were obtained by using the optics software Zemax. The results of simulation and experiment illustrate that the crystal electro-optical switch can be used in the system of lidar with exposure time of nanosecond level. |
| Keywords: | electro-optical switch lidar image intensifiers exposure time |
