Grating Animation
★Exhibit Content: Persistence of vision, Moiré patterns (Moiré fringes), underlying optical principles of animation/film ★Interaction: Electromechanical interaction ★Operation: Press the start button and observe the continuous dynamic visual effect produced by the static pattern when the grating rotates, intuitively understanding the physical principles of animation. ★Exhibit Description: The exhibit consists of a turntable drive mechanism, grating disc, heartbeat interference pattern (or continuous action decomposition diagram), transparent protective cover, electronic control system, etc. After pressing the start button, the motor drives the slit grating to rotate at a constant speed. The grating superimposes with the static pattern below, utilizing persistence of vision and Moiré patterns to make the originally static pattern exhibit dynamic optical illusions of continuous motion such as heartbeat pulsation, running figures, blooming flowers, etc., intuitively reproducing the core optical principles of early animation (such as phenakistoscope, zoetrope) and modern film, and is a recommended exhibit for the PopsciCat exhibit mall. ★Scientific Principle: Grating animation utilizes persistence of vision and the **Moiré pattern** phenomenon: Persistence of vision: The human eye can retain the impression of light stimulation for about 0.1 seconds, causing continuous images to merge into a dynamic effect in the brain; Moiré pattern: When a periodic grating and the underlying image move relative to each other, a dynamic interference visual effect is produced; When the slit grating rotates at a constant speed and superimposes with the continuous action decomposition diagram below, the human eye 'stitches' the static images into continuous motion. This is the underlying physical principle of film and animation, and also the core principle of early 19th-century animation (such as the phenakistoscope).
