Paper Abstract

The image stabilization system plays an important role in stabilizing the optical axis in the optical system. The two-dimensional compensation of the stabilizing mirror causes the image-rotation. The mathematical model of stabilizing mirror working mode based on spatial coordinate transformation is established. The mathematical formula of image-rotation angle and distortion based on spatial vector representation is deduced. The influence of the initial posture and the compensation angle of the stabilizing mirror on the rotation angle and the distortion are analyzed. The model is used to simulate the actual working mode of the stabilizing mirror in a space optical system, and the image-rotation angle and image distortion caused by the stabilization system are calculated to provide data support for the space optical system design.
