    Abstract: 本論文主要討論如何製作出以一般點光源重建出可環繞觀賞的實像影像黑白化之圓盤型複合全像術。
    ;In this study, we discuss how to create a 360-degree viewable real achromatic image disk-type holographic stereogram.
    To produce an achromatic effect, we will extend the viewing window, then the diffraction light of different wavelength will overlap and generate the achromatic image. In order to achieve that, we will use tow-step holographic process. In the first step, we will set a diffuser in the master optic system to extend the viewing window. In the second step, we will divide the master hologram into two prat which can offer red light and blue light, then reconstruct part of master hologram to reconstruct the diffraction light of different wavelength. At the same time, we can control the partial width and the exposure energy of tow part to obtain the distribution of diffraction light color.
    Using the two-step holographic process, we can expend the viewing widow and create the viewing widow which can observe achromatic image successfully. And controlling the exposure energy can obtain the variety of diffraction light color. Finally, we will select a suitable light source as the reconstruction light to make the image be more ideal and achieve the achromatic image effect.
