The circularviewing hologram can show 360° reconstruction of a object, so it has a great application value. For the purpose of increasing the viewingangle of the image and reconstructing it by white light, a new two steps method, Which combined computer with optical holography for making the circularviewing hologram, was proposed considering of the computer generated hologram. First, the algorithm of computer generated circularviewing plane hologram was studied, the propagation principle of object wave was derived, and the distribution pattern of the object wave on the recording plane was obtained meanwhile. Next, the influence of the angle between reference light and object light on spatial frequency of the hologram was discussed, the spatial frequency could be decreased by using a point reference light source, so it could increase the viewingangle. However, the image could only be viewed by laser. To solve this problem and to reconstruct the hologram by white light, optical setup for imageplane hologram was designed as the second step. Then, the relationship between spatial frequency of the hologram and the size of object, and the relationship between spatial frequency of the hologram and the viewing angle were deduced, and the curves of the relationships were also calculated. Finally, a 3D modeling gray object was used and the circularviewing hologram with large side viewing angle which could be reconstructed by white light was made. Therefore, the calculation method and optical design were verified. For circularviewing plane hologram, the technique can record realexisting objects and virtual objects and achieve the image by white light, and it can increase the viewingangle of the reconstruction at the same time.
