Spatial Filtered Pseudocolor Encoding of Holographic Image by Rainbow Holography with Synthesized Slit

采用空间滤波合成狭缝彩虹全息术对二维透射物进行假彩色编码。记录二维透射物的不同空间频谱所对应的物象时，参考光处于不同的传播方向，同时将透镜平移，全息图在白光再现时就出现不同颜色。

Spatial filtered pseudocolor encoding of holographic image for two - dimensional transparent object by rainbow holography with synthesized slit is proposed. The technique described here requires the recordings of rainbow holography with synthesized slit for the different images of the object corresponding to the different spatial filters used on the same plate, each of which is recorded with a specific orientation of the reference beam. During each expurse the lens is displaced by a distance. The result is that each scence is encoded with a specific color under conjugate white - light reconstruction.
