Paper Abstract

Absolute measurement of spherical surface by use of point diffraction interferometer (PDI) has been studied both theoretically and experimentally. By the estimation of optical error, 10-3 (lambda) rms can be expected as absolute accuracy. Experimental results with high accuracy have been obtained.
