Reconstruction of the experimental autocorrelation function and determination of the parameters of the statistical roughness of a surface from laser radiation scattering in an integrated-optical waveguide

The possibility of using the waveguide scattering of laser radiation for obtaining information on the statistical properties of irregularities from the noisy data obtained in the far-field zone is shown. A complex algorithm for reconstructing the experimental autocorrelation function of the surface roughness of an integrated-optical waveguide substrate is described. This algorithm is based on a combination of the classical regularisation and quasi-optimal filtering.
