Modeling of the light retroreflection properties by the lattice of tetrahedral retroflectors

Abstract

The features of scattering of laser radiation by diffraction gratings consisting of a set of tetrahedral retroreflectors are considered in the article. In the process of physical and computer simulation, the influence of various lattice parameters on the spatial characteristics of the reflected radiation was investigated. The obtained dependences indicate that the power of the scattered radiation is concentrated on a small area of the receiving area and essentially depends on the observation conditions, as well as the characteristics of the reflecting system and the parameters of the illumination radiation.
