Turn the knob to adjust the frequency of the strobe light and observe the presentation effect on the turntable.
Scientific Principles:
The most important principle of film and animation is "visual persistence". Scientific experiments have proved that the human eye can still make the image of an object remain on the retina after the disappearance of a certain vision1-0.In about 4 seconds, the film rotates at a constant speed of 24 frames per second, and a series of static images will create a continuous visual impression due to the visual persistence, producing a realistic sense of movement.
Energy Demand:220v 400w
Knowledge Point Expansion:The principle of visual persistence refers to the fact that when the human eye observes a scene, the light signal is converted into a neural signal, which is then processed in the brain. Due to the special physiological structure of the human eye and brain, the objects we see do not disappear immediately with the disappearance of light, but remain on the retina for a period of time, which is about 1 24 seconds. That's why movies like movies and TV are continuous**.
When we watch a movie, there are 24 still images per second in rapid succession**, and our brain combines these images into a continuous moving picture due to the visual persistence effect. The same principle applies to areas such as television, gaming, and virtual reality.
The principle of visual persistence not only explains why we see continuous moving images, but also reveals the physiological mechanisms of the human eye and the way the brain processes visual information. This principle has a wide range of applications, not only in the entertainment industry, but also in science, technology, and medicine. For example, in animation, animators can use the principle of visual persistence to control the movements and expressions of characters to achieve a more realistic effect. In the medical field, doctors can use the principle of visual persistence to observe the physiological changes and pathological processes of patients.
In conclusion, the principle of visual persistence is a very important scientific principle, which not only reveals the physiological mechanism of the human eye and the way the brain processes visual information, but also provides important theoretical support and practical guidance for applications in many fields.
