METHOD FOR PRODUCING HOLOGRAM LENS, METHOD FOR PRODUCING HOLOGRAM COLOR FILTER, AND SPACE LIGHT MODULATING APPARATUSES USING THE HOLOGRAM LENS AND THE HOLOGRAM COLOR FILTER RESPECTIVELY |
摘要 |
A thickness of each hologram lens for forming a hologram color filter is set so as to be smaller as the wavelength of light to be diffracted by each hologram lens is shorter. A thin plate glass layer is bonded to a surface of the hologram color filter such that it is in a firm contact therewith by adhesive agent and a sum of the thickness of the thin plate glass layer and thickness of the adhesive agent is smaller than the shortest focal length of the focal lengths in glass of a plurality of the hologram lenses. As a result, light diffracted and divided by the hologram color filter is focused on a picture element electrode of a corresponding color properly thereby eliminating deterioration of color reproduction due to mixing of colors. Further, upon production of the hologram color filter from hologram recording material, an influence of a fringe rotation is compensated.
