摘要
在一定条件下,体积全息图会出现分岔现象。当衍射效率达到某一临界值时,随着衍射效率的提高,带宽将明显加宽,用白光再现体积全息图已不可能。本文对这一问题进行了分析,并得出结论,在白光再现条件下,体积全息图的衍射效率存在极限,此极限值为94.7％。
Under certain conditions, the phenomenon of bifurcation may rise in volume holograms. When the diffraction efficiency reaches some critical value, the bandwidth of volume hologram will extand obviously with the increase of diffraction efficiency. It is unable to recoustruct volume holograms by white light. This problem is analyzed, and a conclusion is obtained, under the condition of recoustruction with white light, the diffraction efficiency of volume hologram has a limit, its value is calculated as 94.7％.
