碩士 === 國立中央大學 === 光電科學研究所 === 92 === Abstract A reflection hologram has a unique property of high wavelength sensitivity . Therefore, we combine it with our disk-type multiplex holography to increase its capability. This is because we could take advantage of the property of reflection hologram to make true color disk-type multiplex holograms come true. Before that, we have to increase the vertical viewing window of the reflection hologram to get better observation condition. First of all, we make a transmission master hologram (H1). In this process, we apply a diffuser on the object wave in the optical system to diffuse it in the vertical direction. Then we copy the transmission master hologram (H1) as a reflection transfer hologram(H2). By varying the concentration of triethanolamine(TEA), we could change the wavelength of the diffracted wave. That is to say, we are able to change the color of the reconstruction image by pre-soaking the unexposed plate in triethanolamine liquid of different concentrations to produce a true color hologram. At the end of this thesis, we introduce a method to roughly improve the 3D image performance for our true color hologram .
