摘　　要：接触法复制全息图需要使母全息图与感光干板的乳胶面相向紧密接触,对母全息图进行透射照明,经冲洗处理后的曝光干板即为普通的全息图.采用低压钠灯为光源,对菲涅耳全息图进行复制实践,复制全息图的再现像清晰度比母全息图要差,但就像的质量而言层次很分明.Copying hologram by the contact method requires close contact of the original hologram with the subject plate before light exposure. After exposure, development and fixation, a new copy of the original hologram is obtained. By using low-power Na light source, the Fresnel hologram is copied. Although the definition of image reproduced from the copied hologram is lowered, the overall quality of the image is good.
