摘　　要：本文分析了全息图视角受限制的主要原因，其原因是再现衍射光方向受到限制。针对这个原因，作者提出了同步旋转参考光、物体和干板，采用分时记录物体的信息，使全息图再现时形成多方向的衍射光波，从而达到扩大视角之目的。文章中给出了理论分析和实验装置及结果。In this paper we analysied the reason of the limited viewing-angle of a hologram is the limited direction of the reconstruction diffraction light. In view of the limitation, we proposed a method of enlarging the viewing-angle by synchronously rotating the object.the reference light and the holographic plate to record the object at different times. When the hologram is reconstructed, it will generate multi-direction diffraction light and we will see it with a large viewing-angle. We carried out the principle of the method and proposed a experimental configuration and gave out the result.
