Paper Abstract

In this paper, an expression which relates the normalized ensemble average of central peak intensity in the far field speckle pattern to the variance and correlation length of a rough surface under measurement is derived theoretically. On this basis, a new method of measuring surface roughness is suggested, and computer simulation experiment is conducted. The results obtained are in good agreement with the theoretical analysis.
