Abstract

In the given operation the experimental procedure of measuring of indicatrixes of coefficient of brightness and scattering matrix of surfaces of various materials is featured at their irradiation by pulsing laser radiation in the plan with combined by a radiant and receiver of radiation. The experimental results received on a wavelength 532 nm at intensity approximately 10⁴W/cm² at a pulse length approximately 10 ns for a dairy glass MC-20 and corrosion- proof steels H18N10T with root-mean-square deviations of height of a lateral view of a roughness of explored surfaces R_z, laying in a gamut 0.025-2.5 mkm ($DEL6-14 classes of processing of a surface) are given. The discussion of the received results is carrying out.
