Paper Abstract

This report describes recent research in application of interferometry to measurement of the aberrations of full spheres using an extension of subaperture testing theory. Theoretical and numerical studies have substantiated the method. Experimental validation has been done by comparison with mechanical roundness traces. Direct comparison is impossible because both methods suffer from misalignment errors. In this paper, a data reduction technique is developed for the mechanical roundness traces and comparison is made of the reduced data from both methods.
