A study on make volume type color holographic stereogram using the DLP project
Abstract
We studied on optical setup to produce volume color holographic stereogram in a digital method.Optical setup was designed by adopting a DLP projector for the production of volume color hologram simplifiedand automated compare to existing exposure methods used film. A parallax image was projected to the diffuseplate using a DLP projector and object beam was created. Reference beam was illuminated in the oppositedirection of emulsion side and volume color hologram was made by interference with the object beam. Theparallax image was color separated and made into red, green and blue components. The color holographicstereogram was recorded using etch color components by spacial division exposure. We produced the colorholographic stereogram by dividing it into two steps using three laser beam having the wavelengths of 660nm,532nm and 457nm. The color holographic stereogram was produced in a Lippmann hologram type usingreconstructed the real image by a conjugation reconstruction in the master hologram. We confirmed thatvolume color holographic stereogram realization is possible with the suggested digital method optical setup.
