Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of apparatus for demonstrating of optical illusion phenomenon, is specially a kind of trapezoidal optical illusion demonstrator.
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.Wherein, common, the most most widely used is geometrical optical illusion.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, the Special Equipment clearly can demonstrating, can accurately differentiate again geometrical optical illusion is lacked.
Summary of the invention
The purpose of this utility model is the trapezoidal optical illusion demonstrator belonging to geometrical optical illusion designing the clear demonstration of a kind 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 rectangle base plate, first trapezoidal, the second trapezoidal, the first laser instrument, second laser, wherein: first trapezoidal be positive isosceles trapezoid, second is trapezoidal for falling isosceles trapezoid, and the first trapezoidal short base is equal with the second trapezoidal long base length; First trapezoidal, second be trapezoidally all fixed on backplate surface, second trapezoidal be positioned at first trapezoidal immediately below, first trapezoidal, the second trapezoidal axis of symmetry overlaps; First laser instrument and second laser are separately fixed on base plate, directly over the first two ends, trapezoidal short base, first laser instrument and second laser send trapezoidal with first, that the second trapezoidal axis of symmetry is parallel the first laser rays and the second laser rays respectively, wherein the first laser rays is respectively through the left end on the first trapezoidal short base and the second trapezoidal long base, and the second laser rays is respectively through the right-hand member on the first trapezoidal short base and the second trapezoidal long base.
The beneficial effects of the utility model are: clear observation also accurately can differentiate trapezoidal optical illusion phenomenon.When observing trapezoidal optical illusion phenomenon, close the first laser instrument and second laser, now to seem more trapezoidal than second long bottom side length many on the first trapezoidal short base.When differentiating optical illusion phenomenon, open the first laser instrument and second laser, by the first laser rays and these two parallel rayss of the second laser rays, can judge that the first trapezoidal short base is equal with the second trapezoidal long base length.The utility model 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 plate, 2. first is trapezoidal, and 3. second is trapezoidal, 4. the first laser instrument, 5. second laser, 21. short bases, 31. long bases, 41. first laser rays, 51. second laser rays, 231. axis of symmetry.
Embodiment
As shown in Figure 1, the utility model comprises trapezoidal 2, second trapezoidal 3, first laser instrument 4 of rectangle base plate 1, first, second laser 5.First trapezoidal 2 be positive isosceles trapezoid, second trapezoidal 3 for fall isosceles trapezoid, the short base 21 of first trapezoidal 2 is equal with long base 31 length of second trapezoidal 3.First trapezoidal 2, second trapezoidal 3 is all fixed on base plate 1 surface, and second trapezoidal 3 is positioned at immediately below first trapezoidal 2, and the first trapezoidal axis of symmetry 231 of 2, second trapezoidal 3 overlaps.
First laser instrument 4 and second laser 5 are separately fixed on base plate 1, directly over the first trapezoidal 2 two ends, short base 21, first laser instrument 4 and second laser 5 send the first parallel laser rays 41 and the second laser rays 51 of the axis of symmetry 231 of 2, second trapezoidal 3 trapezoidal with first respectively, wherein the first laser rays 41 is respectively through the left end on the first trapezoidal 2 short bases 21 and the second trapezoidal 3 long bases 31, and the second laser rays 51 is respectively through the right-hand member on the first trapezoidal 2 short bases 21 and the second trapezoidal 3 long bases 31.
When the first laser instrument 4 is not opened with second laser 5, the short base 21 of first trapezoidal 2 seems that the long base 31 of more trapezoidal than second 3 is much longer.Open the first laser instrument 4 and second laser 5, by the first laser rays 41 and these two parallel rayss of the second laser rays 51, can clear judgement to be sandwiched in the short base 21 of first trapezoidal 2 between these two parallel lines equal with long base 31 length of second trapezoidal 3.
