The method of the analysis of luminous flux diffusion on the lateral surface of an optical fiber as a basis for designing and manufacturing of side-hole optical fibers is presented. The idea of the controllable emission of the luminous flux by formation of the fiber lateral surface is described. The presented method was verified by manufacturing an optical fiber with controllable emission from the...
Analysis of luminous flux transfer through a conical ring-core light guide is presented. Three optical guides of this kind are the main elements of an original instrument for measurement of the luminance distribution in the field of view constructed by the authors. It was found that in the case of the output surface perpendicular to the symmetry axis of the cone having vertical angles greater than...
