Abstract

Abstract

The image rotating phenomenon occurs in the China "HY——1A" satellite ocean color temperature scanner because the onboard K mirror is unable to work, and it impacts the quality of satellite images.The multi-pixel scanning track of 45° rotating scanning mirror with K mirror is analyzed based on the vector theory of optical refraction.First, the K mirror's angle is searched automatically based on the theory of image relativity.Second, the rotating image is corrected by the K mirror's angle and the theory of multipixel scanning.Finally, a usable corrected-image is obtained.
