Aerial Imaging
Operation: 1. Press the start button; 2. Observe the fan blade rotation phenomenon. Function Overview: The exhibit consists of a swing rod, LED lights, a motor, etc. Visitors press the 'Start' button and observe the image changes presented during the rotation of the swing rod. Scientific Principle: Why does an image appear on the rotating plane of the fan blade? When the human eye observes a scene, light signals are transmitted to the brain through the optic nerve to form vision, but after the light effect ends, the visual image in the brain does not disappear immediately, but stays for 0.1 to 0.4 seconds. This is the persistence of vision phenomenon of the human eye. There is an LED light group on the fan blade. When rotating, the circuit controls the LED lights to emit light according to program instructions. The light emitted at each position on the rotating plane is part of a complete image. Due to the persistence of vision effect, the image of the luminous point will be retained in the brain for a short period. Therefore, the image of the luminous point at each position on the rotating plane of the fan blade will be retained by the brain. These retained images of luminous points are superimposed with the luminous points currently being seen, and a complete image is seen in the air. The playback of movies, television, and animated films is designed and produced using the persistence of vision effect of the human eye. Look around, which other exhibits utilize the persistence of vision phenomenon?
