摘　　要：通过分析全息图记录的干涉条纹图样，指出对于二维全息图，一束再现光将产生两个对称于全息图面的物象，两束对称于全息图面的再现光将产生位形相同的物象；三维全息图的再现，象的对称性不变，但原物象的对称再现象有一定的弥散，对称光再现时，等亮度再现象出现在全息图转动一个角度之后。With the analysis of interference fringe pattern recorded by hologram,authors point out that 2 D hologram will produce two object images symmetrical about the hologram plane when it was reconstructed with single beam,and will produce the same object image in shape when it was reconstructed with two beams symmetrical about hologram.For 3 D hologram,the symmetry of the reconstructed image will not be changed,but the symmetrical reconstructed image of the original object image was somewhat diffuse.When it was reconstructed by symmetical beam,the reconstructed images with equal brightness were displayed after the hologram was rotated somewhat of its position.Finally a distinct image plane reflection hologram of trnasmission rainbow hologram has been made.
