摘　　要：彩虹全息术中的长狭缝演化为一个点，可极大提高再现像的亮度，文中阐述了这种闪耀型彩虹全息图制版光路，论证了在明视距离处形成出射瞳孔实像的条件，指出了这种多色显示的全息图有高信噪比。: When the slit used in the rainbow holography reduces to a point, the brightness of the reconstructed image will be greatly enhanced. This paper describes the light path implemented in making the holographic plates of this shinestyle rainbow hologram and provide the condition in which a real exitpupil image can from in a clear visual distance. The paper also points out that this kind of holographic plates, which display multicolour has a high signaltonoise (S/N) ratio.
