Description

Using the rainbow holographic technique, a color or an achromatic image can be obtained from the superposition of various rainbow holograms. In the present work, an analysis of the reconstruction process of a multiple rainbow hologram using a simulation program that includes Kogelnik's theory is performed. The objective of the analysis performed in this work is the searching of adequate recording conditions to improve the luminance of the final reconstructed image. Comparison between experimental data and calculations are shown. The effects of shrinkage and hologram tilting on the diffraction efficiency of the holograms in function of the wavelength are evaluated quantitatively.
