description: Development of an optical polarimetric scheme for improvement of fin-gerprint systems is considered. Method based on Mueller matrix imaging (with 36 measurements) of scattering object using Lu-Chipman polar decomposition algorithm in order to calculate polarimetric characteristics. To convert images to the numerical matrices, a Matlab program code was written, in which the Lu-Chipman algorithm for the polar decomposition of the Mueller matrix was also implemented. As test experiments, the angular dependences of the ele-ments of the Mueller matrix for the polarizer and the quarter-wave plate were taken. Experiments were made with real fingers and several dummies made of gelatin and white glue. Proposed scheme and calculating algorithm showed promising results for solving the problem of improving the security of finger-print sensors. Further studies can be aimed at determining the possibilities of integration, miniaturization of the set-up, simplifying measurement process, testing other algorithms for decomposing the matrix and organizing a database of biometric parameters.
