碩士 === 國立中央大學 === 光電科學研究所 === 95 === The main purpose of this research is to prove that one can fabricate a full-color reflection hologram for 360° walk-around viewing with one laser source. TEA solution, which could change the thickness of film, is adopted, and then the pre-soaked film is used to record interference patters. Utilizing the measurement of the diffracted angle, the swelling ratio α of the film can be from the theory model. α as a function of TEA concentration is also plotted for later reference. Utilizing the calculations of direction cosines for diffracted ray, we simulate the holographic process by a computer. From the simulated results, we know that if we want to use a laser to produce a full-color reflection-type image-plane disk-type holograms, we have to design the parameters for hologram production, including the position of the straight viewing window, swelling ratio, the concentrations of TEA solutions, and the position of the converging reference wave. The above-mentioned fabrication parameters are discussed in this thesis. Finally, some experimental results are demonstrated. We can see that viewing windows for diffracted waves belonging to different wavelengths are retrieved at the same place (desired viewing window) as we designed. So we can say that it is possible to produce full-color reflection-type image-plane holograms for 360° walk-around viewing.
