Abstract

The invention relates to a dynamic stereoscopic presentation device for showing an afterglow effect. The dynamic stereoscopic presentation device comprises a rack and a turntable shaft system, wherein the turntable shaft system comprises a rotary shaft mounted on the rack and a turntable which is fixed on the rotary shaft and rotates synchronously with the rotary shaft; a rotary drum rotating coaxially with the turntable is fixed on the turntable; a plurality of stereoscopic models uniformly spaced along the circumferential direction of the rotary drum and forming a continuous action posture are arranged on the outer side surface of the rotary drum; a plurality of reference marks arranged along the circumferential direction of the rotary drum are uniformly spaced on the surface of the turntable; the reference marks are located on the outer side of the rotary drum; the number of the reference marks is one more than the number of the stereoscopic models. The dynamic stereoscopic presentation device provided by the invention is simple in structure, convenient to use and suitable for long-term teaching. Visitors or learners can understand the phenomenon of vision persistence and the principles of animations and films more visually; the dynamic stereoscopic presentation device is suitable for long-term teaching.

Description

technical field [0001] The invention relates to a dynamic three-dimensional demonstration device for displaying afterglow effects, 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, and the photoreceptor cells are sensitive to light, and convert the light signal into neural current, which is transmitted 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 a 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 a movie is actually a continuous picture printed on a strip ...
