Embodiment Construction
[0014] Such as figure 1 As shown, the present invention includes a base plate 1, a strip plate 2, a push-pull rod 3, and a guide rail 4; the base plate 1 and the strip plate 2 are rectangular, and the strip plate 2 is no less than 7 pieces, along the direction of the width of the strip plate 2 Arranged up and down in sequence, each strip plate 2 has the same shape, and the surface of the strip plate 2 is provided with a black square 21 and a white square 22 whose side length is equal to the width of the strip strip 2, and the black square 21 and the white square 22 are arranged along the strip shape. The long sides of the plates 2 are arranged alternately; the length of the strip plate 2 is equal to an odd multiple of its width; the back of each strip plate 2 is provided with a guide rail 4 along the long side direction of the strip plate 2, and the strip plate 2 passes through the guide rail 4 and the bottom plate 1 is movably connected and can move left and right along the l...

The invention discloses a visual illusion demonstrating instrument for parallel lines. The visual illusion demonstrating instrument comprises a base plate, strip-shaped plates, push-pull rods and guide rails, wherein the base plate and the strip-shaped plates are rectangular; the number of the strip-shaped plates is larger than or equal to 7; the strip-shaped plates are sequentially arranged in a manner of leaning to each other up and down in the wide side direction of each strip-shaped plate; the strip-shaped plates are the same in shape; black square blocks and white square blocks are alternately arranged on the surface of each strip-shaped plate; the length of the strip-shaped plates is equal to the odd times of the width of the strip-shaped plates; each strip-shaped plate is movably connected with the base plate by virtue of the guide rail which is arranged at the back of the strip-shaped plate and can move left and right in the long side direction of the strip-shaped plate; the push-pull rods are fixed on the wide side of each strip-shaped plate. The visual illusion demonstrating instrument can be used for generating changeable visual illusion patterns and can be hung in various science and technology museums; by observing with eyes and operating with hands, the deepening of the understanding of the visual illusion phenomenon can be facilitated.
Description
technical field [0001] The invention belongs to the technical field of experimental demonstration devices, and relates to a device for demonstrating optical illusion phenomena, in particular to an apparatus for demonstrating optical illusions of parallel lines. Background technique [0002] Optical illusion is the wrong judgment and perception of the observed object based on empiricism or improper reference when people observe certain objects. There are many types of optical illusions, such as geometric illusions, chiaroscuro illusions, color illusions, shape illusions, motion illusions, and shadow illusions. Optical illusions are widely used in psychology, physiology, physics, design and other fields. Designing an optical illusion observation and identification device is conducive to enriching the content of popular science activities and stimulating students' interest in exploring scientific secrets. [0003] The parallel lines optical illusion is a typical geometric opt...
