基于LABVIEW的激光实验光路调节系统

针对当前大部分超短超强激光实验中真空光路调控效率低、操作方式繁琐等缺点，设计了一种基于LabVIEW软件开发平台的集成化实验光路调节系统来实现对光路高效便捷的调控。该系统由光斑位置采集单元、光斑位置调节单元和计算机等三部分构成，其设计思路是利用激光光斑映射在CCD上的空间位置，实现光路指向定位的反馈，根据反馈信息设计人机交互界面实现光路指向的调控。该系统成功实现多线程并行运行，并将不同型号不同通讯方式的多个位移台控制器集成于同一界面控制。实验证明，与常用的手动调节系统相比，该系统对实验光路的调控更方便快捷，调节效率更高。

Laser path adjusting system for laser experiments based on LabVIEW

For the purpose of overcoming the disadvantages, such as low adjusting efficiency and complicated operating procedures, in most of current ultra-short and ultra-high-intensity laser experiments, an integrated and simple system for laser path adjusting was designed based on LabVIEW software. This system was consisted of three modules, which were named as laser spot acquiring module, laser path position adjusting module and industry computer respectively. In this system, the pointing of laser path was decided by the position of laser incident on CCD camera, and the adjusting of light path in vacuum was accomplished by a person-machine interface. Meanwhile, simultaneous multi-route running has been achieved in this system, and moving stage controllers of different models or communication styles have been integrated in the same interface. Experiments show that this system could be a better choice for more convenient adjusting of laser path and higher efficiency of ultra-short and ultra-high-intensity laser experiments.
