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 special track, and the test board is installed on the test car. The height of the test board is different from the height of the tester. There are 2 test boards Pattern with background color, 2 patterns arranged in parallel, same pattern, different size, the pattern is composed of 1-6 concentric circles composed of the same rhombus, the pattern is provided with rectangular coordinates, the origin of the coordinates is the center of the concentric circles, and the linear track. 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 as an experimental demonstration device or a game device and method for optical visual effect observation test.

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
