Investigation of methods for the formation of multicolored images reconstructed with protective holograms

Abstract

Dot-matrix holograms contain diffraction gratings with different periods and orientations. Grating parameters (period and orintation) are calculated according to input data, which is graphic raster file. Traditionally image uses additive color model RGB, which involves limited color range. To increase color range International Illumination Commission (ICI) color model is considered. In this paper methods for calculating the parameters of diffraction gratings with different periods and orientations for ICI graphic files are investigated and analyzed.
