Abstract: This paper presents the prospect,preparing method of the reflecting volume holographic pictures.Before the plate was explored,it was soaked in TEA solution.After explored and chemically processing,the emulsion thickness was changed,so the wavelength of the volume grating and the color of the reconstructed image were changed,too.This paper indicates the relationship of the TEA concentration to color of the reconstructed image,the making method of multicolor hologram in a plate,and points out how to compensate the differences of the diffraction efficiency and color difference.
