Abstract:	反射式圓盤型複合全像術是由本實驗室鄭益祥教授與謝易辰學長，在2004年發展出來，其物光架構加入毛玻璃擴展反射式圓盤型全像片的垂直視窗，其研究完成了展示單色物體影像給環繞四周的觀察著同時觀賞的反射式全像片。平面型母片有商業上可以大量生產的優點，本論文研究「平面型母片之反射式彩色圓盤型複合全像術」，我們將會介紹如何製作可環繞觀賞的反射式彩色全像片。在論文中，我們先介紹各種製作反射式彩色全像片的方法。之後，我們選擇利用單支雷射去製作RGB三張母片。藉著改變物光與參考光系統的入射角度，觀察者在適當條件下，可以在設計的視窗接收到三張母片的繞射光影像資訊。為了達到用全像術的方法製作出反射式彩色圓盤型複合全像術，我們介紹幾種方法去調整影像的放大率、成像面的位置、成像面位移量。 Image-plane technique for “Reflection disk-type multiplex holography” was developed in 2004. Light shaping diffuser was utilized in the object-beam system to expand the vertical view window of a reflection disk-type hologram. This hologram can display monochromatic 3D object image for 360o walk-around viewing simultaneously. The planar master hologram has the advantage of possibility for commercial mass production. In this thesis, we will introduce how to make a color reflection image-plane disk-type multiplex hologram for walk-around viewing. We first introduce several kinds of methods to fabricate colorful reflection holograms. Then, we describe the method with which single laser is used to fabricate three RGB master holograms. By controlling the incident angles of the object beam and the reference beam, the diffracted image beams from three master holograms can be perceived by the observers situated at designated viewing window. In order to obtain the best holographic process for making color reflection disk-type multiplex hologram, we also demonstrate methods for adjusting the size of object image, the position of image-plane, and the shift of the image-plane under Bragg mismatch condition.
