Optical vision effect testing apparatus and testing method thereof

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, wherein a seat and an arrangement for positioning heads and necks for two tester are fixed on the testing vehicle, the testing vehicle is positioned on the specific raceway, there is a separation angle between the surface of the testing board and the raceway, the height of the testing board is adapted to the height of the tester, the testing board is provided with two patterns with fundamental color, the patterns comprises concentric circles formed from 1-5 identical squares and diamonds, one of them is provided with rectangular coordinates, said head and neck positioning arrangement being a stand type positioning device with adjustable height, the separation angle between the tester's horizontal sight line and the tester's sight line when observing concentric circle centers on the testing board is zero, a rectilinear raceway is employed to produce non-interrupted relative or 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...

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
