Heartbeat Light and Shadow
★Exhibit Content: Moiré fringes (Moiré patterns) optical interference principle, visual illusion science popularization ★Interaction: Electromechanical interaction ★Operation: Press the "Start" button, observe the dynamic changes of the pattern on the turntable, and intuitively experience the visual illusion effect produced by Moiré fringe interference. ★Exhibit Description: The exhibit consists of a 30 square tube + 2.0mm cold-rolled sheet baked paint display stand, 12mm Kelaisi artificial stone countertop, turntable drive mechanism, heartbeat interference pattern grating set, stainless steel start button, electrical control system, etc. After pressing the start button, the motor drives the grating to rotate, and the two sets of gratings interfere to form dynamic Moiré fringes, presenting a visual spectacle similar to "heartbeat light and shadow", allowing the audience to understand the principles of optical interference and visual illusion through interaction. It is suitable for eye health/optics science popularization hall scenes and is a recommended exhibit for the Science Popularization Cat exhibit mall. ★Scientific Principle: This exhibit is based on the Moiré fringe optical interference principle: Moiré fringes are the visual result of interference between two lines/objects at a constant angle and frequency; when the human eye cannot distinguish individual lines/objects, it can only see the pattern formed by interference, namely Moiré fringes; In the exhibit, when the two sets of gratings rotate, the fringe interference produces a dynamic visual illusion, simulating a light and shadow effect similar to a heartbeat, intuitively demonstrating the laws of optical interference. It is a classic visual/optical science popularization exhibit.
