Abstract
A novel algorithm and experiment using phase retrieval to test aspheric mirror without
auxiliary optical elements has been developed. To test aspheric mirror without auxiliary optical
elements, a new algorithm has been invented to overcome the calculation difficulty due to the
significant departure of aspheric surface from a sphere. In this algorithm, the aspheric surface is
fitted into several annular ellipse sub-apertures, and each sub-aperture aberration can be retrieved
the same as ball mirror testing. The whole aspheric surface can be retrieved by stitching all the subapertures
together. An experiment has been carried out to test the validity of this algorithm.
