Abstract

A novel method named radial slope testing for measuring the wave aberration of an optical imaging system with a large aperture is introduced, which is a kind of self referenced testing. A Zernike slope polynomial fitting algorithm is applied to the data processing. The principal of method and construction of system are described, the results of computer simulation testing are presented as well. It is shown that this method is especially useful for wavefront sensing of an active optical system operated on a satellite without any guide star or reference surface.
