摘　　要：分别研究了激光强度、光程、相干长度、缝宽和缝数、狭缝的位置、分束镜分束比和光栅条纹数以及曝光时间对彩虹全息图再现象的影响。用不同宽度的单缝、双缝和三缝作了实验拍摄,对再现象的光能量与色模糊给出理论分析,得到用双缝和三缝拍摄再现象更明亮的结论。适当的激光强度、相干长度及其光栅条纹超过1 000条/mm或分束镜分束比恰当时,彩虹全息图效果明显。与此同时,发现在同一全息图上能观察到透射和反射两个再现象,用共轭的理论解释这种现象。The effects of qualifications are studied to rainbow hologram in this pape. The laser intensity, optical path, different size of slit, slits position, beam splitter mirror and the number of stripes to grating as well as the exposure time are important factors for image. Different width of the single-slit , two or three slits were made by experimental holography. Light energy and colour blurred of reconstructed image are analysed. The reconstructed images by using two or three slits photograph is better. At the same time, transmission and reflection reconstructed images in a rainbow photoram are oberved. We use the theory of conjugate to explain this phenomenon.
