Abstract

A method of interferometrically measuring large convex aspheres using test plates with computer generated holograms was developed at the University of Arizona. We present the results from a set of experiments that demonstrate the accuracy, flexibility, and the simplicity of performing the holographic test. A low-cost stand-alone setup as built for implementing this test on a 38-cm convex hyperboloid. A direct comparison of the CGH measurement with results from a classical Hindle test shows excellent agreement. We also demonstrate the unique attribute of this test to measure bare glass surfaces and highly reflective surfaces without making any modifications to the test equipment.
