Zakirullin R.S., Letuta S.N. GRATING OPTICAL FILTER WITH ANGULAR SELECTIVE LIGHT TRANSMISSIONAn optical filter with thin-film grating layers on both surfaces of the transparent sheet substrate is presented. Relative position of the gratings with alternating transmissive and absorptive strips provides angular selectivity of light transmission. Influence of parameters of plane-parallel and coaxial-cylindrical filters on results of regulation of the directional light transmission are set by a graphic-analytical calculation method.Key words: directional light transmission, optical filter, gratings with alternating strips, angular selective regulation.
