Problems solved by technology

But the above-mentioned result is the result of human observation on the one hand, it will produce different observation results due to the difference in the degree of concentration of the observer's gaze, the speed of the head moving back and forth, and the stability of the head and neck during the movement process; On the one hand, only relying on the forward and backward movement of the human head can only observe for a short time, and long-term observation will cause fatigue in the head, neck and even the whole body
So far, there is no dedicated equipment and method for observing and measuring

Embodiment

[0017] Embodiment: the structure of the present invention is as figure 1 , figure 2 and image 3 As shown, it consists of a test car 1, a special track 2 for the test car to run, and a test board 3. The test car 1 is located on the special track 2. The test car 1 is equipped with a head and neck positioning device, and the test board 3 is located on the track 2. At the other end of the track 2, there is an angle between the surface of the test board 3 and the height of the test board 3 is different from the height of the tester. There are 2 patterns with background colors on the test board 3, and the two patterns are up and down. Arrangements, patterns are different, and sizes are different. One pattern is composed of 4 identical squares composed of concentric circles, and a horizontal line passing through the center of the circle is set on the pattern. There are Cartesian coordinates, and the origin of the coordinates is the center of the concentric circles.

Abstract

Disclosed is an optical visual effect testing device and testing method belonging to the technical field of experiment demonstration device, wherein the testing device comprises a testing vehicle, a specific raceway for running the testing vehicle and a testing board, the testing vehicle is positioned on the raceway, the testing vehicle is provided with a head and neck positioning device, the testing board is positioned on the other end of the raceway, there is a separation angle between the panel surface of the raceway and testing board, the heights of the testing board and the tester are different, the testing board is provided with two patterns with fundamental color, the two patterns are arranged from top to down with different graphs and different size, the patterns comprises concentric circles formed from 1-6 identical squares and diamonds, a rectilinear raceway is employed to produce non-interrupted relative and opposite direction movement between the testing board and the tester, the tester will be able to observe that, the patterns on the testing board will rotate around the center of circle on the circumference counterclockwise or clockwise.

Description

1. Technical field [0001] The invention relates to a test device and a test method for experimental demonstration of optical visual effects, belonging to the technical field of experimental demonstration devices. 2. Background technology [0002] A visual picture of a "rotating circle" was reported in "Visual Games (2)" written by British visual scientist Al Sekel, published by Hainan Publishing House in April 2004 and translated by Hong Fang. The picture is composed of two concentric circles composed of rhombus patterns. When you focus your eyes on the center of the concentric circles and move your head back and forth, you will find that the two concentric circles composed of rhombus patterns will rotate. This phenomenon was discovered in 1999 by Italian vision scientists B. Pina and G. Grystaff. The above research results are very useful for college and middle school students to do demonstration experiments, or to do science popularization work in science popularization a...
