Paper Abstract

Changes in the configuration of an holographic grating have to be anticipated in the fabrication of practical Holographic Diffractive Structures (HDSs) for solar illumination engineering. Because photographic material used in HDSs changes characteristics during processing, there is a change of slant angle (due to shrinkage or swelling, i.e. actual dimensional change of the emulsion) and a change of average refractive index (due to bleaching and fixing). Computer aided analyses of test data have been performed in a way that predicts, under a wide range of conditions and for any given holographic recording material, the exposures required to attain specific intended optimum illumination results. This model has been verified in experiments and has been used to design illumination geometries for HDSs that meet the intended and often site specific target conditions very accurately.
