Abstract

Shearing interferometry is employed for the analysis of basic statistical properties of rough curved surfaces. Using this method the root-mean-square values (standard deviations) of heights and slopes of the surface irregularities are determined. Moreover, autocorrelation lengths and functions of the surfaces mentioned are evaluated. A statistical analysis of randomly rough parabolic mirror collimators is performed by the method presented.
