Abstract
An optical vision effect testing device, belonging to the field of laboratory technology demonstration device, consists of a testing vehicle, an exclusive track for the testing vehicle running and a test plate; the testing vehicle is located on the exclusive track, fixed with a seat and a head-neck allocation device for two surveyors, the test plate is fixed and installed on the other test vehicle. The height of the test plate and the surveyor are equal. The test plate is provided with two patterns in different sizes with bottom color, made up of concentric circles which consist of 1 to 6 identical segments. The right angle coordinate is set on the pattern. The intersection angle, between the sight to the level of the surveyor and the sight to the concentric center on the test plate the surveyor observed, is 0; the track is linear. Driving two test vehicles to make an uninterrupted relative and opposite movement between the surveyor and test plate, the surveyor will see that the patterns on the test plate rotate anticlockwise and clockwise along central of 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, by test carriage, the dedicated track and the test board that are used for the test carriage operation are formed, test carriage is positioned on the dedicated track, fix a seat on the test carriage and be used for the device that two tester's incidence are located, test board is fixedly mounted on another test carriage, be positioned at the other end of dedicated track, the height of test board and tester's height adapt, test board is provided with the pattern of 2 band background colors, 2 pattern magnitude differences, the concentric circles that pattern is made up of 1-6 identical line segment constitutes, and this pattern is provided with rectangular coordinate, and true origin is the concentric circles 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.
Described dedicated track is a kind of rectilinear orbit.
During test, regulate the incidence locating device, make two bit test person incidence location and respectively observe a pattern, sight is kept a close watch on the center of circle all the time; Drive two test carriages, make between test carriage and the test board and carry out relative and move toward one another incessantly, 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 arrangement mode difference of line segment 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, by test carriage 1, the dedicated track 2 and the test board 3 that are used for the test carriage operation are formed, test carriage 1 is positioned on the dedicated track, fix a seat on the test carriage 1 and be used for the device that two tester's incidence are located, test board 3 is fixedly mounted on another test carriage 1, be positioned at the other end of dedicated track 2, the height of test board 3 and tester's height adapt, test board 3 is provided with the pattern of 2 band background colors, 2 pattern magnitude differences, the concentric circles that pattern is made up of 4 identical line segments constitutes, and this pattern is provided with rectangular coordinate, and true origin is the concentric circles 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 that the height of described test board is higher than the tester is meant, the angle position 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 rectilinear orbit.
During test, regulate the incidence locating device, make two bit test person incidence location and respectively observe a pattern, sight is kept a close watch on the center of circle all the time; Drive two test carriages, make between test carriage and the test board and carry out relative and move toward one another incessantly, 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 arrangement mode difference of line segment on adjacent two circumference on the test board, the rotation direction of the figure that the observer sees is also different with angular velocity.
