Abstract

To test the shape of aspherical surfaces whose axial curvature is zero, a new holographic interferometer is introduced. The interferometer comprises a cube beam splitter and a plane mirror, and utilizes both first and zero-th order diffracted waves. This paper describes the algorithm to make the computer generated hologram as well as the design aspect of holographic interferometer.
