Abstract
The utility model discloses a line segment length visual illusion demonstration appearance, including the luminous line segment of base, light source, first luminous line segment, second, the base be the rectangle, first luminous line segment, second isolychn segment length equal, respectively the horizontal symmetry axle of perpendicular base inlay and locate the base surface, the light source sends light A, light B, light C, light D totally four bundles of light, wherein light A, light B pass through the upper and lower both ends of first luminous line segment respectively, light C, light D are respectively through the give off light upper and lower both ends of line segment of second. The utility model discloses be favorable to the observation and the resolution of visual illusion, be favorable to deepening the understanding to the visual illusion phenomenon.
Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of optical illusion apparatus for demonstrating, is specially the short-sighted illusion demonstrator of a kind of length along path.
Background technology
Line segment equal for length is placed on some with in the background of specific lines time, due to be subject to lines background vision interference, these isometric line segments look and can seem different in size.At present, lack a kind of clear observation and differentiate the special demonstration equipment of the short-sighted illusion of this length along path.
Summary of the invention
The purpose of this utility model is the short-sighted illusion demonstrator of a kind of length along path designing the clear demonstration of energy and be conducive to illusion resolution.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: comprise base, light source, first luminous line segment, second luminous line segment, described base is rectangle, described first luminous line segment, the length of the second luminous line segment is equal, first luminous line segment, the horizontal symmetry axis of the second luminous line segment vertical feet is respectively embedded at susceptor surface, first luminous line segment, the mid point of the second luminous line segment is positioned in base horizontal symmetry axis, light source is fixed in the base horizontal symmetry axis on the left of the first luminous line segment, light source emits beam A, light B, light C, light D is totally four bundle light, wherein light A, light B is respectively through the two ends up and down of the first luminous line segment, light C, light D is respectively through the two ends up and down of the second luminous line segment.
Described first luminous line segment, the second luminous line segment are LED isolychn.
Owing to adopting above-mentioned design, the utility model can produce following beneficial effect: when light source is not opened, and can judge that the length of the first luminous line segment, the second luminous line segment is completely equal; After light source is opened, its four bundle light formation background interference sent, the length now near the first luminous line segment of light source seems the length being obviously greater than the second luminous line segment, presents optical illusion thus.The utility model can be located at all kinds of science popularization place, is conducive to observation and the resolution of optical illusion, is conducive to deepening the understanding to optical illusion phenomenon.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is formation schematic diagram (when light source is not opened) of the present utility model.
Fig. 2 is the schematic diagram (when light source is opened) that the utility model forms optical illusion.
In figure: 1. base, 2. light source, 3. the first luminous line segment, 4. the second luminous line segment, 11. horizontal symmetry axis, 21. light A, 22. light B, 23. light C, 24. light D.
Embodiment
As shown in Figure 1, base 1 is rectangle, the length of the luminous line segment 4 of the first luminous line segment 3, second is equal, the horizontal symmetry axis 11 of the luminous line segment 4 of the first luminous line segment 3, second vertical feet 1 is respectively embedded at base 1 surface, the mid point of the luminous line segment 4 of the first luminous line segment 3, second is positioned in horizontal symmetry axis 11, and light source 2 is fixed in the horizontal symmetry axis 11 of the base 1 on the left of the first luminous line segment 3.
As shown in Figure 2, light source 2 emit beam A21, light B22, light C23, light D24 totally four bundle light, wherein light A21, light B22 are respectively through the two ends up and down of the first luminous line segment 3, and light C23, light D24 are respectively through the two ends up and down of the second luminous line segment 4.Now the length of the first luminous line segment 3 seems the length being obviously greater than the second luminous line segment 4, forms optical illusion thus.
The luminous line segment 4 of first luminous line segment 3, second is LED isolychn, is convenient to clear observation.
