Development of full-color volume hologram printer

Abstract

In previous study, we had developed multi-color volume hologram printer which output 2 color components holograms. This system required manually switching of the laser when output a different color component. Furthermore, the reconstructed image was biased in color because proposed hologram piled up the color component holograms. In this study, we developed a full-color volume hologram printer with three lasers whose wavelength are primary colors and multiple exposure method. A fringe pattern is calculated with respect to each wavelength. Calculated fringe pattern is displayed on LCoS and exposed for each wavelength of laser.
