We simplify the structure of “image-plane disk-type multiplex”. Removing the third lens, so that the viewing window is composed of divergent. We obtain 3D image with higher magnification after this simplification. In this study, we focus on magnification and diffraction efficiency. We first introduce the divergent how to form an image. Trying to improve the image quality adjustment the divergence angle and the angle of incidence of object beam. With computer simulation, we analyze the holographic model of disk-type hologram under white-light reconstruction. By the changing values of the hologram number and the wavelength corresponding to the observed image points, we can obtain the image change of the reconstructed image under different observation distances, disk size, laser and various vertical viewing angles. Using this fabrication method, we obtain very large image. The disadvantage of this method is the deformation and black stripes. Finally, we propose some improved methods and the possible future development.
