摘　　要：报道了应用纵向分割多狭缝曝光彩虹全息术合成多幅断层图像为三维消色像的方法及其实验结果。通过将主全息图记录狭缝按纵向分割并结合使用循环分割和色散补偿光栅 ,实现了在较高的分辨率和较低色模糊的多幅断层像的白光三维消色像的合成 ,并提高了再现像的视觉亮度、视场和立体感。A novel method and the experimental result of the vertical area partition for recording the elemental master holograms in a multiple exposure rainbow holography are reported. By using this vertical area partition of the recording material to record the elemental master holograms in cycle, 3 D achromatic synthesis of a set of 2 D patterns can be reconstructed. Combined with a plane diffraction grating to compensate the horizontal dispersion during the reconstruction, a bright 3 D synthesized achromatic images with a wider vertical viewing angle, higher resolution, and lower color blur have been obtained in white light reconstruction.
