摘要
为满足条纹相机便携化、智能化的发展需要,研制了一种高适用性的分布式智能控制系统,实现了对条纹相机工作参量的监测,对电极电压、扫描工作模式的精确控制以及对图像的采集与处理.基于物联网技术框架与客户端-服务器的结构模式,实现了有线及无线设备扩展的多机协作功能与移动监控功能.并针对该控制系统,设计了具有自保护功能的自激型反激式可调高压电源模块,基于自激式拓扑的简单结构,实现了电源的小型化,且线性调整准确度可达1%.采用Nd∶YLF脉冲激光器(脉宽8ps,波长526.5nm)对应用该控制系统的可见光皮秒条纹相机进行标定,测试得到动态分辨率为12.75Lp/mm(CTF=14%),动态范围为234∶1,时间分辨率达到14ps.
A distributed intelligent control system was implemented to make streak cameras more protable and intelligent, which achieved the monitoring of working parameters, precise control of the electrode voltage and scanning patterns, additionally, image acquisition and processing. Based on the structure of Internet of things and client-server model, the system realized multimachine collaboration capabilities about wired and wireless devices extension and mobile monitoring. Furthermore, an adjustable self-protection high voltage ringing choke converter was designed for the system. The power supply realized the miniaturization by the simply self-excited topological structure, and its linear adjustment accuracy can reach 1%. The picosecond visible light streak camera with the intelligent control system was calibrated by the Nd：YLF pulse laser （Wavelength of 526.5 nmand pulse width of 8 ps）. A dynamic spatial resolution of 20 lp/mm （CTF=14%）, a dynamic range of 234 ： 1 and a temporal resolution of 14 ps were reached.
