Abstract. The problems of manufacturing of projection screen for target environment simulating stand are considered. Raster reflecting surface with directional-diffuse light reflection is chosen for the projection screen. Dependence of the reflective surface brightness characteristics on the angle of light flux reflection is analyzed. Method of cooling of the screen surface operating in the visible and infrared spectral regions is defined in accordance with selected technology of the raster manufacturing. A technology for sphere cutting to approximate its shape is developed.
Keywords: projection screen, raster reflecting surface, spectral brightness, target environment imitation stand
