This paper describes the results of the investigation of the laser radiation interaction with metal surface. The investigations were performed of the effect of the pulse-periodic laser radiation on the material surface. Laser diagnostics of the interaction area was realized using a laser monitor (projection microscope). The method of reconstruction of three-dimensional relief was developed and realized based on the two-dimensional surface image by use of the dependence of pixel brightness on the tilt angle of the surface microplates. The correlation coefficients of the reconstructed reliefs were determined.
