[Abstract]:The solar magnetic field plays an important role in the study of solar physics. The high-resolution observation image of the solar magnetic field is the main basis for studying the small-scale activities of the sun. NVST has been able to make high-resolution imaging observations of the sun at present. A high-resolution magnetic imaging instrument is being developed. This paper is also based on the relevant work carried out. In order to realize the measurement of solar magnetic field, it is necessary to calibrate the polarization of telescope system and magnetograph. In this paper, the calibration measurement scheme of KD*P polarization analyzer is designed, and the measurement scheme of beam splitter in high resolution magnetic imaging instrument is designed. The polarization effect of different beam splitter is measured and compared. It is of great significance to calibrate the polarization characteristics of beam splitter mirror and to choose the scheme of beam splitter mirror. The high-resolution magnetic imaging instrument designed by NVST uses synchronous reconstruction technology to realize the high-resolution magnetic field observation of the sun. Therefore, the data acquisition mode used in the magnetic imaging instrument is very important, which will directly affect the synchronous reconstruction of the image. In this paper, the data acquisition scheme of high resolution magnetograph is discussed, and the influence of the characteristics of KD*P polarization analyzer and CMOS camera on synchronous reconstruction is analyzed. The main innovations of this paper are as follows: the experiment of parameter measurement for KD*P polarization analyzer is designed, the high precision measurement of Mueller matrix of beam splitter is realized by air Mueller matrix calibration method, and the high resolution magnetic imaging instrument for NVST is developed. The data acquisition model is discussed. A synchronous testing system for KD*P and COMS cameras is proposed.
