Color moiré simulations in contact-type 3-D displays.

A new method of color moire fringe simulation in the contact-type 3-D displays is introduced. The method allows simulating color moires appearing in the displays, which cannot be approximated by conventional cosine approximation of a line grating. The color moires are mainly introduced by the line width of the boundary lines between the elemental optics in and plate thickness of viewing zone forming optics. This is because the lines are hiding some parts of pixels under the viewing zone forming optics, and the plate thickness induces a virtual contraction of the pixels. The simulated color moire fringes are closely matched with those appearing at the displays.
