Moire Fringes
★Exhibit Content: Moiré Patterns ★Interaction: Mechanical Interaction ★Operation: Rotate the disc and observe the changes in the image as the disc rotates. ★Exhibit Description: The exhibit mainly consists of a set of Moiré pattern rotating discs, recommended by PopsciCat Exhibit Store. When the disc rotates rapidly and its speed increases, the audience will see different content changes. ★Scientific Principle: Moiré patterns are usually produced by superimposing two dense-line graphics with constant angle and frequency. The most notable feature of Moiré patterns is that a slight positional change of the two graphics can cause a large-scale change in the pattern. Moiré is an interference image produced by overlapping grid-like stripes. Moiré is actually a manifestation of the beat principle: when stripes with slightly different spatial frequencies are superimposed, due to the difference in stripe spacing, the overlapping positions gradually shift, forming beats.
