Optical vision effect testing apparatus and testing method thereof

Abstract

An optical visual effect testing device and a testing method belong to the technical field of experimental demonstration devices. It consists of a test car, a special track for the test car to run, and a test board. The test car is located on the track. The test car is equipped with a positioning device for the head. The test board is located outside the track. The height of the test board is different from that of the tester. There are 2 patterns with background color on the board, the patterns are arranged up and down, and the pattern and size are the same. They are all composed of concentric circles composed of 1-6 identical squares. There is a horizontal line passing through the center of the circle and a straight track on the pattern. There is uninterrupted relative and opposite movement between the test board and the tester, and the tester will see that the pattern on the test board rotates counterclockwise or clockwise along the center of the circle on the circumference. The invention can be used not only as an experimental demonstration device and method for optical visual effect observation test, but also as a game device and method.

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
