Abstract

为了满足1m新真空太阳望远镜高分辨率磁像仪对图像采集的需求,研制了基于5 KD*P偏振调制和同程异构的图像同步采集时序控制系统。通过对KD*P的偏振调制特性和6 s CMOS相机的Rolling曝光及外触发工作特性进行详细分析,设计了同步控制时序,并给出7了系统的工作流程。在深入研究工作时序各参数之间的相互制约关系,并对各时间参数随8机波动量进行了大量的实测和统计分析之后,得到了系统运行的时序条件。最后在几种工9作状态下对时序系统进行了实测,从而证明了所设计的时序控制系统满足磁像仪对KD*P偏10振调制和同程异构的序列斑点图同步采集的要求。 

Other Abstract

In order to meet the requirements of image acquisition of the high resolution magnetograph installed at 1 m new vacuum solar telescope, the timing sequence control system based on KD*P polarization modulation and image synchronization acquisition for different structure of optical path is developed and depicted in this paper. The scientific requirements of the The polarimetric characteristics of KD*P, the Rolling exposure mode of sCMOS camera and its external trigger on the control system is given in section 1. And based on this, the synchronization-control timing sequence was designed and the workflows of the system with different parameters are given in section 2. Then each parameters of the timing sequence are analysed and their fluctuation are carefully measured and analysed statistically. The constraints on the timing sequence of the system are then defined. The implementation and the test result of different workflows are given in the final part and the results shows the design of the system could meet the given requirements on the accuracy of the synchronised acquisition.
