为了实现可见光波段多路不同波长激光的高精度合束与发射,设计了一套用于激光指向误差监测的紧凑型光学监测装置。根据光电跟瞄发射系统对激光合束与发射精度的应用需求,提出了光束指向监测装置的设计指标。在明确监测装置应用空间的基础上,分别对装置的光电探测器、光学系统和机械结构进行了详细设计,采用上下分层多次折叠的光学设计有效压缩了监测装置的轴向尺寸。完成精密加工、装调后,对光束指向监测装置的焦距、调制传递函数和监测精度进行了实验检测。结果表明:所设计的光束指向监测装置不仅体积小(200 mm×180 mm×140 mm)、焦距大(约1 002 mm),而且对光束指向的监测精度高(优于10.0 μrad),满足光电跟瞄发射系统的应用需求。
To accurately combine and launch several visible laser beam with different wavelengths, a compact optical monitoring device for beam direction was designed. First, main performances of the monitoring device were measured based on the application requirement of combining and launching laser systems. Subsequently, photo detect, optical system, and mechanism structure of the monitoring device were selected or designed using the application space of device. The length of the monitoring device was compressed considerably using the six times folding beams and upper and lower layered optical path. Finally, the monitoring device was tested for focal, modulation transfer function (MTF), and monitoring accuracy by conducting experiments after carefully manufacturing, assembling, and adjusting. The results show that the designed monitoring device with low volume (200 mm×180 mm×140 mm), long focus (approximately 1 002 mm), and high monitoring accuracy (more than 10.0 μrad) can satisfy the application requirements of combining and launching laser systems.
