Moire Windmill

Optics & Eye Health

★Exhibit Content: Moiré Patterns ★Interaction: Mechanical Interaction ★Operation: Step on or pull the rope to rotate the pinwheel and observe the changes in the pinwheel pattern. ★Exhibit Description: The exhibit mainly consists of eight sets of pinwheel mechanisms, each with an interactive pull rope below. Visitors can step on or pull the rope to trigger mechanical and gear transmission, driving the large pinwheel to rotate. This allows visitors to experience mechanical transmission technology and understand the phenomenon and principle of moiré patterns. The exhibit changes the traditional form and content of pinwheel rotors by designing the rotors with multiple types of moiré patterns. Through diverse interactive forms, it guides visitors to further recognize and understand mechanical transmission technology, moiré patterns, and their principles during the experience. Recommended exhibit for PopsciCat Exhibit Store. ★Scientific Principle: Moiré patterns are an optical phenomenon first discovered by French researcher Mr. Moiré in the 18th century. Technically, moiré patterns are the visual result of interference between two lines or two objects at a constant angle and frequency. When the human eye cannot distinguish these two lines or objects, it can only see the interference pattern. The pattern in this optical phenomenon is the moiré pattern.
