In television and digital photography, a pattern on an object being photographed can interfere with the shape of the light sensors to generate unwanted artifacts. In printing, the printed pattern of dots can interfere with the image. Moiré patterns appear in many situations. For the moiré interference pattern to appear, the two patterns must not be completely identical, but rather displaced, rotated, or have slightly different pitch. In mathematics, physics, and art, moiré patterns ( UK: / ˈ m w ɑː r eɪ/ MWAR-ay, US: / m w ɑː ˈ r eɪ/ mwar- AY, French: ( listen)) or moiré fringes are large-scale interference patterns that can be produced when a partially opaque ruled pattern with transparent gaps is overlaid on another similar pattern.
