| Summary: | 碩士 === 國立中央大學 === 光電科學研究所 === 95 === Reflection hologram has the property of high wavelength selectivity. In this thesis paper TEA solutions of various concentrations are needed for film swelling. Using this property we can design the viewing slits at a fixed location in the space for various wavelengths. The formation of a reflection hologram is subdivided into two steps: A virtual cone is formed by transferring the information the H1(master) and the H2(transfer). A plan wave which is parallel to the axis of the cone serves as the reference wave. In the second step, the object images recorded in H1 is retrieved at the image plane to act as the object wave. The reference wave for transfer formation is a converging spherical wave which is focused onto a point on the axis of the cone. With well-designed holographic parameters, a green (or blue) colored image can be obtained by pre-soaking the unexposed film in TEA solution of a suitable concentration. Then the finished hologram is suitable for white light illumination and a 3D full-color image can be seen by the observer.
This thesis emphasizes the experimental aspect. It utilizes the two-step process devised in the thesis “Viewing window extension for reflection disk-type holography” and the theoretical model as well as its simulated results in the thesis entitled “The design of viewing slits and the characteristics of diffracted image of full-color reflection disk-type multiplex holography”. Ultimately we successfully fabricate a reflection hologram which can display a full-color 3D images, with white light illumination, for 360° walk-around viewing.
