Paper Abstract

We have developed a toroidal surface measuring interferometer system. One of the key features of our interferometer system is its ability to measure a toroidal surface without a toroidal wave front and a toroidal reference surface. Our optical system consists of a Fizeau interferometer using a spherical wave front. A cross section figure of the test surface is obtained to analyze interference fringes like a striped bar by using the Fourier transform method. We can then connect each cross section over the entire surface figure by rotation of a rotary table. Results of examination show that the accuracy of our measuring system is better than (lambda) /20 P-V.
