| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 97 === The paper mainly focused on studying the analogical data recording and reconstruction using holographical technology. It aims to study principle and optimize the rainbow holography. Holography is divided into in-line and off-line arrangements in terms of design of reference and object light beams. It''s also divided into transmission and reflection holography in terms of light incident direction of reference and object beams. The holographical plate has to go through the procedure of development、fixing、bleaching for yielding the hologram after recording. This paper built different recording arrangements of holography studied development methods of holographical plate. The 3D image reconstruction of hologram discussed diffraction efficiency and viewable angle.
Rainbow hologram is made by two-step method and reconstructed by white light. The reconstructed image can show dispersion multiple phenomenon and yields better vision. The optimization study for reconstructed image depth and color distribution of rainbow holography discussed the influence slit gap size and distance to master hologram.
Holography needs coherent light and gas lasers are nowpopularly applied light source. This paper used laser pointer for holographical to popularize the holographical application due to it''s relatively cheaper price. This paper measured and analysed light coherence and brightness distribution of applied laser pointer.
Three-dimensional color image production is one of the most important developments for display technology in the future. This paper used triethanolamin solution to immerse the holographical plate and discussed the influence of immersed durations as well as solution concentrations of color property of the reconstructed image. The mixed light source used the cheaper laser pointers.
