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 devices positioning the heads and necks of the two testers are fixed on the testing vehicle which is positioned on the track. The testing board is positioned at the other end of the track in a different altitude with the tester and the board face of the testing board and the track form an angle. The testing board is provided with two patterns with background colors; the two patterns are respectively composed of concentric circles formed by one to six same rhombuses and line sections with a Cartesian coordinates, the origin of which is the center of the concentric circles. The horizontal line of sight and the line of sight observing the centers of the concentric circles on the testing board of the testers form an angle. The track is straight. Drive the testing vehicle to make the testers and the testing board move away from or towards each other incessantly, and then the testers can see the patterns on the board rotate clockwise or counterclockwise along the center of a circle on the circumference.

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 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, 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 the track other end, an angle is arranged between the plate face of track and test board, the height of test board is different with tester's height, test board is provided with the pattern of 2 band background colors, all be provided with rectangular coordinate on 2 patterns, true origin is the concentric circles center of circle, and the concentric circles that one of them pattern is made up of 1-6 same diamond-type constitutes, and another concentric circles of being made up of 1-6 identical line segment constitutes.

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 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, regulate the device of incidence location, 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 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, on the test board on adjacent two circumference the shading value of rhombus different different with the arrangement mode of line segment, 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.
