Method for realizing dynamic imaging of radiation and contraction of jellyfish-like image set

Abstract

The invention discloses a method for realizing dynamic imaging of radiation and contraction of a jellyfish-like image set. Two equal-size and long-strip-shaped plane mirrors are fixed on two plates ofeach movable hinge, an elastic belt can control the size of an included angle between the two plane mirrors and an overall position of the two plane mirrors in a space, and an extension line of a vertical intersecting line of a semi-circular instrument is fixed on a horizontal panel; an automatic vortex ring former is fixed on the horizontal panel, a movement direction of a vortex ring in the automatic vortex ring former is arranged on an extension surface of an equal-division surface of the included angle between the two long-strip-shaped plane mirrors, and an illuminating lamp is fixed on the horizontal panel; the method for controlling the different included angles and the space position between two plane mirrors at the elastic belt and researching the law of radiation and contractionmovement of the imaging by the movement of the jellyfish-like vortex ring with the alternately-changed movement direction generated by non-electric power for a long time is realized, the conception isingenious, the manufacture is extremely simple, the effect is obvious, and the method can be popularized to schools and universities and museums of science and technology.

Description

technical field [0001] This patent involves demonstrating the imaging of a moving jellyfish on a plane mirror with varying angles, and the dynamic image of radiation diffusion and contraction formed, which belongs to the field of physical experiments. Background technique [0002] In geometrical optics, imaging is one of the important contents in teaching. It is widely used, from physical experiments to science and technology education and toys, such as two plane mirrors (one is a semi-transparent membrane mirror) parallel demonstration peep infinite, triangular prism Distributed demonstration kaleidoscopes, etc., in order to increase the interest of students in understanding the imaging of plane mirrors, the kaleidoscopes designed by people are very popular. The kaleidoscope images in the prior art are static, or the lens barrel is rotated, or the object that is artificially imaged is driven by a motor. Rotation, or shaking, etc., the angle between these mirrors is fixed, i...

[0002] In geometrical optics, imaging is one of the important contents in teaching. It is widely used, from physical experiments to science and technology education and toys, such as two plane mirrors (one is a semi-transparent membrane mirror) parallel demonstration peep infinite, triangular prism Distributed demonstration kaleidoscopes, etc., in order to increase the interest of students in understanding the imaging of plane mirrors, the kaleidoscopes designed by people are very popular. The kaleidoscope images in the prior art are static, or the lens barrel is rotated, or the object that is artificially imaged is driven by a motor. Rotation, or shaking, etc., the angle between these mirrors is fixed, it is impossible to compare the images of different angles of the mirrors in one device, and the physical content of its dynamic performance is not deep enough, lacking novelty and Creativity, how to realize the plane mirror imaging with variable angle (variable included angle), and the dynamic object does not rely on electric, manual and other artificial drives, and can last for a long time. A comprehensive new experiment that is simple, low-cost, and convenient for students to explore and research. This patent will solve this problem
