Abstract. Indicatrices of the spectral luminance coefficient for surfaces with different microgeometry are compared. Applicability of these surfaces as projection screens for infrared spectral range is analyzed. Peculiarities of directional light reflection from a surface with a regular microrelief in the form of hexagonal spherical cells are demonstrated.
Keywords: raster projection screen, spectral brightness coefficient
