Abstract

Basic holographic characteristics are presented of a newly developed panchromatic ultra-fine grain silver halide light-sensitive material, for RGB recording of reflective holograms. The average size of initial silver halide grains is less than 10 nm. This ensures a large dynamic range, high resolution, diffraction efficiency and signal-to-noise ratio (exceeding 100:1) in RGB reflective holographic recording. The decrease in the diffraction efficiency in the recording of scattering objects is less than 30% from the maximal values, obtained for specular reflection. The analysis of the colour characteristics of reflection holograms is presented for consecutive holographic recording in the blue, green and red spectral regions..
