Moiré fringes are an interference pattern that is formed when two similar grids overlap each other. The result is a series of fringe patterns that change shape when as the grids are translated. One of the more common occurrences of moiré patterns is found in computer monitors and television sets where we see an ordered wavy pattern is superimposed over the screen in a series of ripples. Moiré patterns also are a common problem in scanned images due to interference between the printed dot pattern and the reflection of the image.
Our exploration of the moiré effect in MagLab Omega begins with a series of Java-based experiments of this phenomena. Visit the links below to view our demonstrations of the moiré effect.
