Abstract
We present analytical and experimental results of the microstructuring of movie theater metallic screens. Our objective is to maintain the polarization state of reflected light and to control the distribution of light intensity avoiding hotspots. We derive analytical solutions of surface functions with an axial symmetry (kernel) that produces isotropic and Lambertian scattering. Then we model the diffraction that can occur with such kernels, ranging from a few microns to several hundred microns, and we give illustrations when illuminated by laser beams corresponding to future use of laser projectors. Finally, we discuss some of the challenges associated with the tiling of such kernels and their manufacturing.
