Moire is generally a natural interference phenomenon that occurs when two separate periodic repetitions are stacked at a predetermined angle. Moire fringes appear as curves, ripples and beams having a wavy shape, which are seen when superimposed on the screen display image, and this means that there is a change in light intensity.
