Polarization characteristics of the reflecting metallized diffraction grates

The results of experimental research of Muler's matrices reflecting metallized surfaces with a periodic structure, in the capacity of which diffraction grates are used, are presented in the paper. The analysis of the power distribution of radiation of the different types and of azimuth of the polarization relative to the horizontal reference plane depending on the reflection angle α and orientation angle of grating grooves θ. Functional regularities of the angles' α and θ influence on the polarization characteristics of the reflected radiation of diffraction grate are determined. The role of correlation of the quantity of diffusion and mirror components of the reflected radiation on its polarization characteristics is shown.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
