摘　　要：无扫描激光雷达距离选通成像系统中同步控制装置的研究设计是系统的关键技术之一,直接关系到能否实现距离选通,能否得到目标的选通图像。在成像系统对同步控制装置的性能要求基础上,论文基于复杂可编程逻辑器件CPLD实现了脉冲激光器与选通ICCD摄像机的同步工作。通过VHDL语言设计出了具有纳秒量级的距离选通同步控制电路。此电路可以方便地进行脉冲宽度和延迟时间的选择,从而提高系统的成像质量和作用距离。The design of the Range-gated synchronization control circuit is one of the key techniques in the scannerless lidar imaging system,which is directly related with the imaging of target. On the basis of the performance requirement to the synchronization control circuit of the imaging system,the paper realized the synchronization control of pulse lasers and gated ICCD camera based on CPLD. A nanoseconds range-gated synchronization control circuit is designed based on VHDL language. The circuit can improve its imaging quality and its action distance by conveniently adjusting pulse width and delayed time.
