摘　　要：利用改变光栅空间频率的方法在国产银盐全息版上制作假彩色反射全息图的技术,给出了国产银盐干版制作的全息图的重现色段同三乙醇胺溶液浓度之间的量化关系.在制作H2的过程中,通过控制乳胶的膨胀程度来改变光栅的条纹间距,并同时调整记录光路,从而使全息图在某一特定照明光角度下,图像的不同区域可重现出不同颜色,达到假彩色编码的目的,并给出相应的理论分析和实验结果.A technique of making pseudo-color reflection hologram in homemade silver-halide plate by changing the spatial frequencies of gratings is presented,and the relation between reconstructed color band of the reflection hologram made in homemade silver-halide plate and the concentration of (CH_2OHCH_2)_3N solution is also given. In the process of H_2 fabrication,the grating spacing is altered by controlling the swelling and shrinkage of emulsion,and at the same time the recording geometry is adjusted.Consequently,under certain illumination angle the parts of the holographic image corresponding to different grating spacing reconstruct different colors.Theoretical analysis and experiment results are presented in this paper.
