摘　　要：提出一种将物光波前先分解记录，再合成的二步平板周视彩虹全息术．波前的分解记录与合成彩虹全息图是分别通过转动物体和干板来实现的．记录这种周视全息图，不需要大孔径和其它特殊光学元件，即可获得周视半径大的无象差立体再现象．该方法可直接用于模压全息图母板的制作．A kind of circular viewing rainbow holography on plane holographic plate is proposed, in which a ring object wave front above it is firStly divided and recorded onto n strip Fresnel holograms, then synthesized. Dividing the wave front to record and Synthesizing a rainbow hologram are realized by roasting the object and holographic plate respectively. The technique will need no special or large aperture optical element, and can obtain a no-aberration reconstructing image with large viewing radius. It can be aPPlied to fabrication of embossed master holograms.
