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. The testing vehicle is positioned on the track. The testing board is arranged on the testing vehicle and in a different altitude with the tester. The testing board is provided with two patterns which are arranged up and down and are of the same design and different sizes with background colors; the two patterns are composed of concentric circles formed by one to six same squares. Horizontal lines which pass through the centers of the concentric circles are arranged in the patterns. The track is straight. The tester and the testing board move away from or towards each other incessantly, and then the tester can see the patterns on the board rotate clockwise or counterclockwise along the center of a circle on the circumference. The utility model can not only be used as a laboratory demonstration device and a method of an optical visual effects observing test, but also be used as a game device and a method.

Description

A kind of optical vision-effect testing device

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 optical vision-effect testing device that can effectively carry out the effect optical visual observation test reasonable in design, easy to manufacture, easy to use.

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, test carriage is positioned on the dedicated track, test board is installed on the test carriage, the height of test board is different with tester's height, and test board is provided with the patterns of 2 band background colors, and 2 patterns are arranged above and below, pattern is identical, vary in size, pattern all is made of the concentric circles that 1-6 identical square formed, and pattern was provided with the horizontal line in the center of circle.

The height of described test board is different with tester's height to be meant, 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 angle is arranged.

Described dedicated track is a kind of rectilinear orbit.

During test, two patterns are also observed in turn in tester's incidence location, and sight is kept a close watch on two concentric circles centers of circle in turn; Drive test carriage, make between test board and the tester and carry out relative and 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, foursquare shading value difference 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 1 is positioned on the dedicated track 2, test board 3 is installed on the test carriage 1, 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 patterns are arranged above and below, pattern is identical, vary in size, pattern all is made of the concentric circles that 4 identical squares are formed, and pattern was provided with the horizontal line in the center of circle.

Described dedicated track is a kind of rectilinear orbit.

In above-mentioned effect optical visual method of testing, adjacent two foursquare shading value differences on the test board, the rotation direction of the figure that the observer sees is also different with angular velocity.
