全日面太阳望远镜在轨调焦定标装置及方法
By designing a focusing and calibration device in the full-plane solar telescope, focusing and flat-field calibration are achieved by using the sun's own light source and lens combination. This solves the problems of complex structure, large weight, and high power consumption of existing devices, improves equipment reliability and calibration accuracy, and simplifies satellite resource requirements.

AI Technical Summary
The existing on-orbit flat-field calibration device for the full solar telescope is complex in structure, heavy in weight, has low reliability and high power consumption, which affects the reliability and load capacity of the satellite.
An on-orbit focusing and calibration device for a full-disk solar telescope was designed, including a front telescope, first and second focusing and calibration units, filters, imaging mirrors and detectors. It uses the sun itself as a light source and achieves focusing and flat-field calibration by switching the rotating wheel and lens combination, avoiding the use of additional light sources and motion mechanisms.
It reduces satellite power consumption requirements, improves equipment reliability, simplifies the calibration process, avoids the influence of field of view effects, ensures uniform illumination of the detector target surface, simplifies the calibration algorithm, and saves satellite resources.
