摘　　要：研究了用于三维(3D)展示的大面积拼接菲涅耳合成全息图的制作方法。在研究菲涅耳全息原理与合成全息原理的基础上,解决了菲涅耳合成全息图在再现图像时再现窗口与观察视场不符的问题。利用激光作为记录和再现光源,进行了全息图拍摄实验,实现了大面积、大景深、高质量的三维人像合成全息图的制作。A holographic method for displaying large-scale three-dimensional （3D） portrait is put forward. The method is based on the theory of Fresnel hologram and holographic stereogram, resolving the problem that the reconstruction window does not accord with observation field-of-view. Using laser as a recording and reconstruction source, the hologram experiment is carried out. By this method, 3D portrait hologram with a large scale and large depth-of-field is made, which can be reconstructed by laser.
