DEVICE FOR DEMONSTRATION OF INFORMATION

摘要

Device for demonstration of information has diffuse-reflecting signs and/or diffuse-reflecting body that are placed on broad surfaces of first and second light-conducting elements, respective placement of each diffuse-reflecting figure of first and second raster structures on surfaces of first and second light-conductive element are chosen as coinciding at geometrical axis and/or are displaced with respect to that axis one with respect to another, value of those displacements is chosen not smaller than half of period of raster structure at least at one coordinate with formation of joint diffuse-reflecting body at whole information plane of the device and/or conform fragment of full color image applied to film, at that joint raster body is placed at one axis with the fragment of full color image, and planes of diffuse-reflecting figures of two raster structures and optical density of those D is chosen as varying from minimal to maximal value in direction from peripheral zones of surfaces of first and second light-conductive elements to geometrical center of those, and optical density D of diffuse-reflecting figures is chosen from interval of values 0,2
