Abstract
A testing device of optical visual effect pertains to the technical field of the testing demonstration device, which is composed of a testing vehicle, a special track for the running of the testing vehicle and a testing board. The testing vehicle is positioned on the special track. The testing board is fixedly arranged on the testing vehicle. The tester is positioned in the other end of the special track. The height of the testing board is corresponding to that of the tester. Two patterns with background color are arranged on the testing board. The pattern is composed of a concentric circle comprising same-shaped diamonds, the quantity of which is one to five. The height of the testing board is corresponding to that of the tester, which means the included angle between the horizontal line of the sight of the tester and the line of the sight of the tester when observing the center of the concentric circle positioned on the testing board is zero. The special track is a linear track. The patterns can be observed by each of the two testers separately and the circle center is observed by the sight of the tester. An uninterrupted relative or same-directional movement between the testing vehicle and the tester is made and the tester can see that the patterns of the testing board can be counterclockwise or clockwise rotated along the circle center.
Description
One, technical field
The utility model relates to a kind of proving installation that is used for the experimental demonstration effect optical visual, belongs to the experimental demonstration device technical field.
Two, background technology
The Britain visual science man Ai Er. Sai Keer that Hainan publishing house publishes, translated by Hong Fang in April, 2004 is shown the visual of having reported a kind of " circle of rotation " in " vision recreation (two) ".This picture is made up of two concentric circless that argyle design constitutes, and keeps close watch on the concentrically ringed center of circle when concentrating, when moving forward and backward head, finds that two concentric circless that are made of argyle design can rotate.This phenomenon is found in 1999 by Italian eyesight scientist B. skin Na and G. Gree Si Tafu.Above-mentioned result of study is done lecture experiment for the university students and middle school students, and it is very useful perhaps doing scientific popularization work in popular science propaganda education department.But The above results is the artificial result who observes on the one hand, and its meeting produces different observationss because of the difference of the intensity of observer's sight, speed and the degree of stability difference of incidence in moving process that head moves forward and backward; On the other hand, only depend on moving forward and backward of head part, can only observe the short time, long-time observation can cause the fatigue of the number of people, neck and even whole body.Up to the present, also there be not a kind of Special Equipment and method that is used to observe measurement.
Three, summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of reasonable in design, easy to manufacture, easy to use, optical vision-effect testing device that can effectively carry out the effect optical visual observation test.
A kind of optical vision-effect testing device is made up of test carriage, the dedicated track and the test board that are used for test carriage operation, and test carriage is positioned on the dedicated track; Test board is fixedly mounted on the test carriage, and the tester is at the other end of track, and the height and the tester of test board highly adapt; Test board is provided with the pattern of two band background colors, and the concentric circles that pattern is made up of 1-5 same diamond-type constitutes.
The height of described test board and tester highly adapt and are meant, angle is 0 between the sight line on the horizontal line of sight of tester's sight and the tester's observation test plate during concentric circles center of circle.
The described dedicated track that is used for the test carriage operation is a kind of rectilinear orbit.
During test, two every of bit test person observe a pattern, and sight is kept a close watch on the center of circle all the time; Drive test carriage, make between test board and the tester and carry out relative or move toward one another incessantly, the tester can see that the pattern on the test board is done counterclockwise or clockwise rotated in the center of circle, circumference upper edge; Accelerate or during the movement velocity of the test carriage that slows down, the pattern rotational angular is also accelerated thereupon or slowed down.
In above-mentioned effect optical visual method of testing, the shading value difference of rhombus on adjacent two circumference on the test board, the rotation direction of the figure that the observer sees is also different with angular velocity.
The utility model both can be used as the experimental demonstration device and the method for effect optical visual observation test, also can be used as a kind of game device and method, make people particularly the teenager in the process of recreation, when strengthening game-play enjoyment, deepened perceptual knowledge to effect optical visual.
Four, description of drawings
Fig. 1 is the structural representation of the utility model optical vision-effect testing device.
Fig. 2 is the front view of test board in the utility model.
Wherein, 1, test carriage, 2, track, 3, test board.
Five, embodiment
Embodiment: structure of the present utility model as depicted in figs. 1 and 2, form by test carriage 1, the dedicated track 2 and the test board 3 that are used for test carriage operation, test carriage is positioned at dedicated track 2, test board 3 is fixedly mounted on the test carriage, the tester is at the other end of track 2, and the height and the tester of test board 3 highly adapt; Test board 3 is provided with the pattern of two band background colors, and the concentric circles that pattern is made up of 3 same diamond-types constitutes.
The height of described test board and tester highly adapt and are meant, angle is 0 between the sight line on the horizontal line of sight of tester's sight and the tester's observation test plate during concentric circles center of circle.
The described dedicated track that is used for the test carriage operation is a kind of rectilinear orbit.
During test, two every of bit test person observe a pattern, and sight is kept a close watch on the center of circle all the time; Drive test carriage, make between test board and the tester and carry out relative or move toward one another incessantly, the tester can see that the pattern on the test board is done counterclockwise or clockwise rotated in the center of circle, circumference upper edge; Accelerate or during the movement velocity of the test carriage that slows down, the pattern rotational angular is also accelerated thereupon or slowed down.
In above-mentioned effect optical visual method of testing, the shading value difference of rhombus on adjacent two circumference on the test board, the rotation direction of the figure that the observer sees is also different with angular velocity.
The utility model both can be used as the experimental demonstration device and the method for effect optical visual observation test, also can be used as a kind of game device and method, make people particularly the teenager in the process of recreation, when strengthening game-play enjoyment, deepened perceptual knowledge to effect optical visual.
