| dc.description.abstract | 在「擴展垂直視角之反射式圓盤型複合全像術」與「反射式成像面凹面圓柱型複合全像術」中，使用了先製作母片再翻拍影像到子片的方法，來製作出具有垂直視窗的反射式全像片，但因其需要多步驟才能製作，使得在製程上相當繁雜，所以在本論文中我們提出了，不需製作母片直接單步驟做出反射式成像面凹面圓柱型複合全像片，首先使用「擴展垂直視角之反射式圓盤複合全像術」的第一步驟的光學系統的物光光路，來當成我們的參考光，把物體的資訊放到全像片上，而另一條光路上放置了毛坡璃，再使物光聚焦到毛玻璃上而製造出垂直視窗，最後利用用重複曝光把影像拍攝到全像底片上，接著在重建影像時改變重建光重建全像片的角度，來控制繞射光的角度，進而可以控制狹縫在空間中的位置，最後將全像片彎折成圓柱狀再把白光燈泡視為點光源放置到圓柱的軸心上成為重建光來重建出影像。
本論文的最後利用繞射理論推算繞射光的方向與在空間中形成的3D影像，藉由改變參數來進行數值模擬，我們分析不同之參數對重建影像的影響，進而尋找出較佳之觀賞條件，再探討改良之辦法。

| dc.description.abstract | We used the method of making the master hologram first then recorded the imformation from master onto the transfer hologram for the vertical viewing window in〝Viewing window extension for reflection disk-type multiplex holography〞and 〝Reflection image-plane alcave cylindrical multiplex holography〞,but it needs many steps to be processed that make the procedure become very complex. In order to improve the situation we adopt the〝One step reflection image-plane alcave cylindrical multiplex holography〞without making the master hologram. First ,we adopt the object beam of the 〝Viewing window extension for reflection disk-type multiplex holography〞as our reference beam to image the object onto our hologram, then we put a source line of cylindrical wave onto a deffuser as the object wave for the fabrication of the vertical viewing window.we adopt a plane wave as the reconstruction reference beam to control the direction of the image wavefront from the hologram and the direction of the position of the vertical viewing window.After bending the transfer hologram into a cylinder,a white-light bulb can be used as the illuminating light source for image restruction.
Final, we used the diffraction theory and the computer simulation to calculate the direction of diffraction beam and the position of the 3Dimages ,the characteristics
of the reconstruction 3D images and the methods to improve the quality of images are also discussed by changing the parameter of our experimental setup.
