Abstract:	本論文簡化「成像面圓盤複合全像術」的物光系統架構，將架構的第三面透鏡移除，使成像面以發散光的形式構成觀賞視窗。此種方法擁有令人驚豔的影像放大倍率。　　本論文著重於影像的放大倍率以及繞射效率，首先會介紹發散光形成影像的方法，並實際調整發散光之發散程度、物光記錄角度等參數來改善影像品質。且模擬改變記錄圓盤尺寸、觀賞角度及距離，或選用不同波長的雷射來製作，藉此觀察影像的變化。　　此方法成功地製作出大尺寸的影像。由於影像是由多張全像片所補足，因此會有形變以及條紋。最後我們也提出改進的方法以及未來可能的發展方向。　　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.
