   In this work we developed the methods of measurement of the scattering matrices elements of brightness coefficients for rough surfaces exposed to powerful pulsed laser radiation. An experimental setup to measure these characteristics with the time resolution ~10 **(–9) s is discussed. Experimental results (the indicatrices of the scattering matrix elements of brightness coefficients) for a number of different materials are given.
