摘要
大型光电系统在对运动目标进行成像或跟踪时，要求其光学系统的焦距能够根据探测目标的距离进行实时调整，使得目标能够清晰地成像在光学系统后的探测器靶面上，便于系统对探测到的目标图像数据进行后续处理。文中采用激光测距仪测量运动目标的距离。
To obtain sharpness image, so that the data of target image detected can be follow up processed, the focus of large photoelectric system need to be adjusted in real time when it is tracking moving target. In this paper, an automatic focusing system of large photoelectric tracker with laser range finder is presented. The structure of focusing control circuit and the simulation experimental result are given.
