Abstract
The utility model discloses a line segment length illusion demonstration appearance based on figure disturbs, including the base, first trapezoidal, the second is trapezoidal, the scale, the base be the rectangle, the first trapezoidal positive isosceles trapezoid that be, the second is trapezoidal for falling isosceles trapezoid, first trapezoidal high equal trapezoidal with the second, first trapezoidal, the second is trapezoidal fixes respectively in the surperficial left and right sides of base, first trapezoidal long base and the trapezoidal short base length of second equal, are located same horizontal line, first trapezoidal and the base surface trapezoidal below of second are equipped with a wire casing that is on a parallel with first trapezoidal long base and the trapezoidal short base of second, during the wire casing is located in the scale activity, and removal about the groove along the line. The utility model discloses be favorable to the observation and the resolution of visual illusion phenomenon.
Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of apparatus for demonstrating of optical illusion effect, is specially the line segment length illusion demonstrator of a kind of graphic based interference.
Background technology
Optical illusion is when people observe some object, based on empiricism or improperly with reference to the false judgment formed and perception.The kind of optical illusion has a lot, as color optical illusion, motion optical illusion, geometrical optical illusion etc.Optical illusion all has a wide range of applications in fields such as physics, physiology, architectural design, product design and traffic safety.Design optical illusion apparatus for demonstrating, is conducive to the content enriching activity to popularize scientific knowledge, excites student to probe into the interest of science secret.At present, lack the clear demonstration of energy, be conducive to the Special Equipment accurately differentiating various optical illusion simultaneously.
Summary of the invention
The purpose of this utility model is the line segment length illusion demonstrator of a kind of graphic based interference of design.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: comprise base, first trapezoidal, the second trapezoidal, rule, described base is rectangle, first trapezoidal be positive isosceles trapezoid, second is trapezoidal for falling isosceles trapezoid, first is trapezoidal equal with the second trapezoidal height, first trapezoidal, second be trapezoidally separately fixed at the susceptor surface left and right sides, and the first trapezoidal long base is equal with the second trapezoidal short base length, be positioned on same level line; First is trapezoidally provided with the susceptor surface of the second trapezoidal below the wire casing that is parallel to the first trapezoidal long base and the second trapezoidal short base, rule activity is located in wire casing, can move left and right along wire casing, the length of rule is more than or equal to the length on the first trapezoidal long base.
Described first trapezoidal, second be trapezoidally LED illuminator.
The beneficial effects of the utility model are: first trapezoidal disturb with the second trapezoidal Form Vision under, the short base that the first trapezoidal long base seems more trapezoidal than second is much shorter, produces optical illusion thus.Rule is moved to respectively first trapezoidal, the second trapezoidal below, it is completely equal with the length on the second trapezoidal short base to record the first trapezoidal long base, identifies optical illusion thus.The utility model is conducive to observation and the resolution of optical illusion phenomenon, 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 of the present utility model.
In figure: 1. base, 2. first is trapezoidal, 21. long bases, and 3. second is trapezoidal, 31. short base, 4. wire casing, 5. rules.
Embodiment
As shown in Figure 1, base 1 is rectangle, first trapezoidal 2 is positive isosceles trapezoid, second trapezoidal 3 for falling isosceles trapezoid, first trapezoidal 2 is equal with the height of second trapezoidal 3, first trapezoidal 2, second trapezoidal 3 is separately fixed at the surperficial left and right sides of base 1, and the long base 21 of first trapezoidal 2 is equal with short base 31 length of second trapezoidal 3, be positioned on same level line; Base 1 surface below first trapezoidal 2 and second trapezoidal 3 is provided with the wire casing 4 that is parallel to the first trapezoidal long base 21 and the second trapezoidal short base 31, rule 5 activity is located in wire casing 4, can move left and right along wire casing 4, the length of rule 5 is more than or equal to the length on the long base 21 of first trapezoidal 2.
First trapezoidal 2, second trapezoidal 3 is LED illuminator, to improve the sharpness of observing.
Claims (2)
1. the line segment length illusion demonstrator of a graphic based interference, it is characterized in that: comprise base, first trapezoidal, the second trapezoidal, rule, described base is rectangle, first trapezoidal be positive isosceles trapezoid, second is trapezoidal for falling isosceles trapezoid, first is trapezoidal equal with the second trapezoidal height, first trapezoidal, second be trapezoidally separately fixed at the susceptor surface left and right sides, and the first trapezoidal long base is equal with the second trapezoidal short base length, be positioned on same level line; First is trapezoidally provided with the susceptor surface of the second trapezoidal below the wire casing that is parallel to the first trapezoidal long base and the second trapezoidal short base, rule activity is located in wire casing, can move left and right along wire casing, the length of rule is more than or equal to the length on the first trapezoidal long base.
