A spatial grid structure demonstration device that demonstrates the phenomenon of persistence of vision

Abstract

The invention relates to a space grid structure demonstration apparatus for displaying the visual persistence phenomenon. The space grid structure demonstration apparatus for displaying the visual persistence phenomenon includes a frame and a pallet rotation shafting, wherein the pallet rotation shafting includes a first rotation shaft and a pallet fixed on the first rotation shaft; the first rotation shaft is arranged on the frame through a first bearing pedestal; a space grid structure is arranged on the pallet; the space grid structure and the pallet coaxially rotate following the first rotation shaft; the space grid structure includes a group of planar attitude contour model units which form continuous action; the attitude contour model units are uniformly arranged at intervals in the rotation circumferential direction of the space grid structure; and the planes of the attitude contour model units are parallel to the radial direction of the pallet; the corresponding positions between the adjacent attitude contour model units are connected through a smooth connecting line to form the integrated space grid structure. The space grid structure demonstration apparatus for displaying the visual persistence phenomenon allows a visitor or a learner to understand the visual persistence phenomenon and the principle of animation and films more visually and vividly, and is suitable for long period of teaching.

Description

technical field [0001] The invention relates to a space grid structure demonstration device for displaying visual persistence phenomenon, which is mainly used for popular science education and teaching practice activities. Background technique [0002] Human vision is actually imaged by the lens of the eye, photoreceptor cells photoreceptor, and convert light signals into neural currents, which are sent back to the brain to cause human vision. The whole process takes about 0.1 to 0.4 seconds. When the object in front of you suddenly disappears, the impression of the optic nerve on the object will not disappear immediately, but will last for 0.1 to 0.4 seconds. This phenomenon of the human eye is the phenomenon of persistence of vision. Also known as the "afterglow effect". Persistence of vision is the basis for the formation and dissemination of visual media such as animation and film. The film of the film is actually a continuous picture printed on a plastic film, and eac...

AI Technical Summary

Problems solved by technology

These two kinds of props and devices, the former can show the principle of persistence of vision but not the principle of film, the latter can show the principle of film but the image is not coherent due to the large difference between pictures

To sum up, the current teaching aids are difficult to attract the attention of the audience, it is difficult to stimulate the willingness of the audience to explore, and the teaching effect is not good
