Analysis of the basic statistical properties of randomly rough curved surfaces by shearing interferometry

Applied Optics 24 (1985) 2690–2695

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.
