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。 為了能夠觀賞到黑白化的影像，利用擴展視窗的方式將不同波長的繞射光重疊產生白光，於此，我們採用母、子片的翻拍技術來達到目的。首先於製作母片時的物光系統中加入毛玻璃來擴展視窗。接著在製作子片時，將母片分成可以提供紅光與藍光的兩個部分，利用部分重建的方式來重建不同波長的繞射光以達到分區配色的效果，同時，藉由改變分區寬度與兩區的曝光能量比例來得到繞射光顏色的分佈變化。 使用上述雙步驟的拍攝方式，我們成功的擴展觀賞視窗並製造出影像黑白化的觀賞視窗，利用改變曝光能量的方式可以得到顏色的變化，最後選擇適當的光源作為重建光，使影像更接近白色而達到影像黑白化的效果。 ;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.
