Optical vision effect testing apparatus and testing method thereof

Abstract

An optical visual effect test device and test method, the test device is composed of a test car, a test car running track and a test board, a seat and a tester's head and neck positioning device are fixed on the test car, and the test car is located on the special track for the test board Located at the other end of the special track, there is an angle between the plane of the test board and the special track. There are 1-5 concentric circles composed of the same pattern on the test board, and a horizontal line passing through the center of the circle is set on the pattern. During the test, the tester sits on the test car, and the tester stares at the center of the circle, so that the test car and the test board move relative to each other. The tester will see that the rhombus on the test board will move counterclockwise or Turn clockwise; when changing the speed of the test vehicle, the angular velocity of the rhombus will also change. 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
