A Basic Study Of Holographic Image Reconstruction In Colors Using Blue-Violet Laser Light

In order to develop a technical process to display holographic reconstructed images in colors, it seems to be very important to extend the holographic displayable region of colors, and so the study of displaying process of the reconstructed images in colors with the use of blue-violet laser light (wavelength: 405 nm) seems to be crucial. We have studied how to improve the characteristics of the displayable region of the reconstructed images using blue-violet laser light when time-sharing multiplex reconstructing technique is employed. In this report, we are going to show some improved displaying characteristics of the object with the curved shape, and to propose some useful basic suggestions for a colorful display of reconstructed holographic images when blue-violet laser light is applied.
