Paper Abstract

ABSTRACT The optical systems with large collecting aperture and high resolution are the future development directions of optical systems on orbit. Once on orbit, it needs to correct the misalignment errors in optical system introduced by the effect of various factors. For the purpose of decreasing the complex degree of alignment on orbit and increasing the reliability, the nonlinear function mathematical model between primary mirror misalignments and Zernike coefficients was established. Then a certain simulated off-axis three-mirror system was corrected, the result indicated that the wavefront RMS reduced to 0.02λ. It satisfied the demands of alignment on orbit.
