Abstract
The invention discloses a kind of optical illusion demonstrator based on stripe interference, including demonstration board and active plugboard, the demonstration board is hollow double-side sandwich structure, demonstration plate surface is provided with first window and the second window, first window and the second window are rectangle, second window be located at first window immediately below, it is long with first window while to it is long while be arranged in parallel；Demonstration board side is communicated with the slot of interlayer, active plugboard is inserted in the interlayer of demonstration board through slot activity, active plugboard surface and first window and second the window's position corresponding position are provided with the first inclined stripe and the second inclined stripe, and the fringe inclination of the first inclined stripe and the second inclined stripe is in opposite direction.Simple structure of the present invention, it is easy to operate, be conducive to the demonstration and resolution of optical illusion.
Description
Technical field
The invention belongs to experimental demonstration device technical field, it is related to a kind of optical illusion phenomenon demonstrator, specially a kind of optical illusion demonstrator based on stripe interference.
Background technology
Optical illusion is when people observe some objects, based on empiricism or improperly with reference to the false judgment and perception for being formed.The species of optical illusion has a lot, such as color optical illusion, optical illusion of motion, geometrical optical illusion.Optical illusion suffers from being widely applied in fields such as physics, physiology, architectural design, product designs.Design optical illusion apparatus for demonstrating, is conducive to the content of abundant activity to popularize scientific knowledge, excites student to probe into the secret interest of science.At present, the various special demonstration equipments that can clearly demonstrate and verify optical illusion are lacked.
The content of the invention
The purpose of the present invention is that design is a kind of can clearly demonstrate and be conducive to the optical illusion demonstrator based on stripe interference that illusion is differentiated.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：Including demonstration board and active plugboard, the demonstration board is hollow double-side sandwich structure, demonstration plate surface is provided with first window and the second window, and first window and the second window are rectangle, the second window be located at immediately below first window and first window it is long while to it is long while be arranged in parallel；Demonstration board side is communicated with the slot of interlayer, active plugboard is inserted in the interlayer of demonstration board through slot activity, active plugboard surface and first window and second the window's position corresponding position are provided with the first inclined stripe and the second inclined stripe, and the fringe inclination of the first inclined stripe and the second inclined stripe is in opposite direction.
First inclined stripe, the second inclined stripe are respectively right low left high inclined stripe and left low right inclined stripe high.
The beneficial effects of the invention are as follows：When active plugboard is not inserted into demonstration board, first window and the second window look like about two rectangles of perfect parallelism；After active plugboard is inserted in demonstration board, the first inclined stripe and the second inclined stripe are presented respectively in first window and the second window, now first window and the second window seem no longer parallel, it appears that the side of first window is upturned, and thus produces optical illusion.Active plugboard is pulled out from demonstration board, you can carry out the resolution of illusion.Simple structure of the present invention, it is easy to operate, be conducive to the demonstration and resolution of optical illusion.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is composition schematic diagram of the invention.
Fig. 2 is the schematic diagram that the present invention produces optical illusion pattern.
In figure：1. demonstration board, 2. active plugboard, 11. first windows, 12. second windows, 13. slots, 14. interlayers, 21. first inclined stripes, 22. second inclined stripes, 23. handles.
Specific embodiment
As shown in Figure 1, demonstration board 1 is hollow double-side sandwich structure, the surface of demonstration board 1 is provided with the window 12 of first window 11 and second, and the window 12 of first window 11 and second is rectangle, the second window 12 be located at immediately below first window 11 and first window 11 it is long while to it is long while be arranged in parallel.The side of demonstration board 1 is communicated with the slot 13 of interlayer 14, active plugboard 2 is inserted in the interlayer 14 of demonstration board 1 through the activity of slot 13, the surface of active plugboard 2 is provided with the first inclined stripe 21 and the second inclined stripe 22 with the position corresponding position of 11 and second window of first window 12, and the first inclined stripe 21 and the second inclined stripe 22 are respectively right low left high inclined stripe and left low right inclined stripe high.
As shown in Fig. 2 active plugboard 2 is entirely insertable in the interlayer 14 of demonstration board 1, now, the first inclined stripe 21 and the second inclined stripe 22 are presented respectively in the window 12 of first window 11 and second.Under the vision interference of the first inclined stripe 21 and the second inclined stripe 22, the right side of first window 11 seems slightly upwardly to tilt so that first window 11 seems no longer parallel with the second window 12, thus produces optical illusion.
Claims (2)
1. a kind of optical illusion demonstrator based on stripe interference, it is characterised in that：Including demonstration board and active plugboard, the demonstration board is hollow double-side sandwich structure, demonstration plate surface is provided with first window and the second window, and first window and the second window are rectangle, the second window be located at immediately below first window and first window it is long while to it is long while be arranged in parallel；Demonstration board side is communicated with the slot of interlayer, active plugboard is inserted in the interlayer of demonstration board through slot activity, active plugboard surface and first window and second the window's position corresponding position are provided with the first inclined stripe and the second inclined stripe, and the fringe inclination of the first inclined stripe and the second inclined stripe is in opposite direction.
2. a kind of optical illusion demonstrator based on stripe interference according to claim 1, it is characterised in that：First inclined stripe, the second inclined stripe are respectively right low left high inclined stripe and left low right inclined stripe high.
