Abstract
The utility model provides an optical visual effects testing device, which relates to the technical field of laboratory demonstration device and consists of a testing vehicle, a special track for the testing vehicle to run on and a testing board. A seat and two positioning devices positioning the heads and necks of two testers are fixed on the testing vehicle which is positioned on the special track. The testing board is positioned outside the special track and in an altitude matching with the altitude of the two testers; the testing board is provided with a pattern with background color. The pattern is composed of concentric circles formed by one to five same rhombuses and is provided with a Cartesian coordinates, the origin of which is the center of the concentric circles. The head and neck positioning devices are height-adjustable and socket type positioning devices. The angle between the horizontal line of sight and the line of sight observing the centre of the concentric circles on the testing board of the testers is zero degree. The track takes the shape of an arc. The testers move back and forth before the testing board incessantly, then the testers can see the pattern on the board rotate clockwise or counterclockwise along the center of a circle on the circumference.
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, form by test carriage, the dedicated track and the test board that are used for test carriage operation, fix a seat on the test carriage and be used for the device that two tester's incidence are located, test carriage is positioned on the dedicated track, test board is positioned at outside the track, and the height and the tester of test board highly adapt; Test board is provided with the pattern of band background color, and the concentric circles that pattern is made up of 1-5 same diamond-type constitutes, and pattern is provided with rectangular coordinate, and true origin is the concentrically ringed center of circle.
Described incidence locating device is a height-adjustable cassette type locating device, this locating device is made up of vertical pivot, transverse slat and riser, vertical pivot is fixed on the test carriage, and transverse slat is installed on the vertical pivot by the transverse slat regulating tank, and riser is installed on the transverse slat by the riser regulating tank.
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.
Described dedicated track is a kind of arc-shaped rail.
During test, two bit test persons observe same pattern, and sight is kept a close watch on the center of circle all the time; Drive test carriage, make test carriage carry out back and forth movement incessantly in the test board front, the tester can see that the pattern on the test board is done in the center of circle, circumference upper edge counterclockwise or clockwise rotated; 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.

Five, embodiment
Embodiment: structure of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 3, form by test carriage 1, the dedicated track 2 and the test board 3 that are used for test carriage operation, fix a seat on the test carriage 1 and be used for the device that two tester's incidence are located, test carriage 1 is positioned on the dedicated track 2, test board 3 is positioned at outside the track, and the height and the tester of test board 3 highly adapt; Test board 3 is provided with the pattern of band background color, and the concentric circles that pattern is made up of 2 same diamond-types constitutes, and pattern is provided with rectangular coordinate, and true origin is the concentrically ringed center of circle.
Described incidence locating device is a height-adjustable cassette type locating device, this locating device is made up of vertical pivot, transverse slat and riser, vertical pivot is fixed on the test carriage, and transverse slat is installed on the vertical pivot by the transverse slat regulating tank, and riser is installed on the transverse slat by the riser regulating tank.
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.
Described dedicated track is a kind of arc-shaped rail.
During test, two bit test persons observe same pattern, and sight is kept a close watch on the center of circle all the time; Drive test carriage, make test carriage carry out back and forth movement incessantly in the test board front, the tester can see that the pattern on the test board is done in the center of circle, circumference upper edge counterclockwise or clockwise rotated; 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.
