BASIC HOLOGRAPHIC CHARACTERISTICS OF PANCHROMATIC LIGHT SENSITIVE MATERIAL FOR REFLECTIVE AUTO STEREOSCOPIC 3D DISPLAY

摘要

Basic holographic characteristics of a newly developed panchromatic ultra-fine grain silver halide light sensitive material for RGB recording of reflective holographic screen for auto stereoscopic 3D display are presented. The average grain size is less than 10nm which ensures a large dynamic range and high resolution, diffraction efficiency and signal to noise ratio (more than 100:1) in RGB reflective holographic recording. The decrease of the diffraction efficiency in reflection holographic recording of scattering objects is less than 30% from the maximal values for specular reflection. The analysis of the color characteristics of the reflective holographic screen for the needs of an auto stereoscopic 3D display with single and multiple viewing zones is presented on the basis of so called "sandwich" structure of two layers for separate holographic recording in blue, green and red spectral regions.
