Magnetic field is one of the primary observational parameters of solar physics. Current research on solar magnetic field observation is moving towards the era of large field of view, high temporal and spatial resolution, high polarization measurement accuracy, and space observation. Full-disk vector MagnetoGraph (FMG) payload equipped with solar magnetic field observation equipment with high time resolution and high spatial resolution will be carried on the Advanced Space-based Solar Observatory (ASO-S). This paper discussed the application of large area high frame rate Complementary Metal Oxide Semiconductor (CMOS) image sensors for solar magnetic field observations in response to the needs of FMG payload feasibility. Based on the principle of filter-type solar magnetographs, we compared the characteristics of different CMOS imager sensors, and found that the CMOS imager sensor with the global shutter is the most suitable for the FMG aboard the ASO-S satellite. We also discussed a laboratory test system for the CMOS sensors, and measured the pixel gain and its distribution. Furthermore, observational test and verification experiments were implemented through the full-disk solar magnetic detection telescope at Huairou Solar Observing Station, Chinese Academy Sciences, with satisfying results. The most favorable CMOS detectors are specified based on the studies.
