Paper Abstract
A new computer generated hologram (CGH) zone-plate common path interferometer which can be used for testing an aspherical mirror with large aperture is presented. A CGH zone- plate made by laser beam drawing is used as the null optical element and its diffraction of (0, 0) and (+1, +1) orders are used as reference light and test light, respectively. Therefore, stigmatic points can be formed so as to use spatial filter effectively to get rid of extraneous light. As a result, fringes with high S/N can be obtained.
