Aerial Imaging
★Exhibit Content: Persistence of vision, aerial imaging, afterimage effect ★Interaction: Electromechanical interaction ★Operation: Press the start button, the swing rod drives the pattern to rotate at high speed, observe the dynamic imaging effect of text/patterns floating in the air, and explore the scientific principle of persistence of vision. ★Exhibit Description: This exhibit is a wall-mounted electromechanical interactive science popularization exhibit, composed of a high-speed swinging rod, pattern display module, drive motor, control circuit, etc. It is a recommended exhibit for the KexMall exhibit mall. The exhibit utilizes the persistence of vision effect of the human eye. When the swing rod rotates back and forth at high speed, the sequentially lit patterns will form a continuous visual afterimage in the human eye, allowing the audience to see complete text and patterns floating in the air, as if the patterns are suspended in the air. By starting the device and observing the dynamic imaging effect, the audience can intuitively experience the magical visual phenomenon brought by persistence of vision and understand the physiological mechanism of visual imaging. ★Scientific Principle: When the human eye observes a scene, it takes a short time for the light signal to be transmitted to the brain nerves. After the light effect ends, the visual image does not disappear immediately. This residual vision is called an "afterimage", and this phenomenon of vision is called "persistence of vision". When the swing rod rotates at high speed, patterns at different positions appear quickly in sequence, and the human eye integrates these intermittent visual signals into a continuous, complete image suspended in the air, achieving the effect of aerial imaging. This is also the core principle of dynamic imaging technologies such as animation and movies.
