Abstract

The space solar observation equipment takes the spacecraft as the platform, and the vibration of spacecraft will have influence over the observation. Therefore, we need to develop the image stabilization system to ensure the imaging resolution. In this paper, a method for detecting the centroid deviation of solar facula is proposed. A photodiode-based deviation detector was designed based on the requirements of the image stabilization system for the Full-disc vector Magneto Graph. Compared with the traditional method of deviation detecting, it has faster response rate, lower power consumption. Backup design is added to improve the reliability of the work on orbit. According to the test results, a resolution of 5 μm is achieved within the working range. It can cooperate with the steering mirror mechanism to form the image stabilization system and serve the Full-disc vector Magneto Graph.
