A method of quantifying moires on 3D displays

A method of quantifying the amount of moires in contact-type 3-D displays is described. The color moires in the displays are induced by the periodic blocking of a part of each pixel on the panel by the boundary lines or the barrier lines consisting of the viewing zone forming optics. The method starts calculating the intensity of an image laden with moires and that of the image with no moires. The moires contrast is defined as the intensity difference of the two images. The contrast values match well with those from the simulated moires for the crossing angle range of 0 degrees to 20 degrees.
