    Abstract: 2013年蘇育緯學長提出「影像前浮式之反射式成像面圓錐型複合全像術」,在水平維度與垂直維度的繞射光皆聚焦至觀測點上,觀賞者會看到前浮在圓錐上方近其對稱軸的三維立體實像。
    ;“Reflection-type image-plane concave conical multiplex holographyˮ was proposed by Y. W. Su in 2013. Both in the horizontal and in the vertical dimensions the reconstructed image wave is focused onto the designated observation point for each individed image-plane hologram. The observers around the hologram can perceive a 3D real-image near the symmetry axis of the hologram cone during reconstruction.
      In this study, first of all, in order to amend for the “astigmatic effectˮ, which is caused by bending the hologram, we should place a cylindrical lens in the reference beam, and for different radius of hologram cone, we should rotate the axis of the cylindrical lens to specific angle. Secondly, we analyze images under the influence of different horizontal focal point for the image wave which is observed at the same observation distance. By using the computer simulation to trace all the relevant rays and compare the variation of the hologram numbers and the observed wavelength of the image points corresponding to different horizontal focal point, we can find out the change of the width-to-height ratio of the reconstructed image under different observation distances. We use the method of image simulation to amend the deformation caused by hologram bending. Finally, in order to increase the dimension of the vertical viewing window, we use a white-light source with a line filament to reconstruct the hologram.
