Marching in Formation
★Exhibit Content: Persistence of Vision ★Interaction: Electromechanical Interaction ★Operation: Turn the handwheel to activate the strobe light, observe the changes in the motion picture of the model figures, and explore the principle behind it. ★Exhibit Description: The exhibit mainly consists of a turntable, figure models, and a strobe light. It is a recommended exhibit from the PopsciCat Exhibit Store. The exhibit utilizes the persistence of vision of the human eye. If the visual stimulus signals from the observed object are spaced less than 1/24 second apart, the vision cannot disappear in time, thus creating an illusion of continuity. If a flashing light is used to illuminate the rotating turntable, when the motion frequency of the figure models on the turntable matches the flash frequency, it is as if the strobe light is "frozen" at a certain position, forming a still image. In this way, a series of still images of specific patterns form the continuous motion of the "figures". ★Scientific Principle: When the human eye observes a scene, the light signal is transmitted to the brain nerves, which takes a brief moment. After the light action ends, the visual image does not disappear immediately. This residual vision is called an "afterimage", and this phenomenon of vision is known as "persistence of vision".
