Inverse problem of theory of the laser irradiation scattering in two-dimensional irregular integrated optical waveguide in the presence of statistic noise

The linear inverse problem of the theory of the light scattering in two-dimensional integrated optical waveguide with statistical irregularities in presence of noise (non exact data) is investigated. The approximated correct solution of the inverse problemo of the theory of wavegiude scattering in hand is obtained for the natural physic and mathematics restrictions, of imposed on a "measured" scattering pattern. The algorithm of restoring an autocovariance function of waveguide irregularities is based on a combination of classic fegularization and quasi-optimal filtration. © 2005 by Astro Ltd.
