Optical visual effect testing device

Abstract

An optical visual effect checkout gear and its measuring method belong to technical sphere of experimental demonstration device, in which the checkout gear consists of test carriage, test carriage orbit and test board. An armchair seat and a cervical locating device for conner are mounted on the test carriage, the test carriage is located on the special orbit; the test board is located outside the special orbit and the altitude of test board is higher than the conner altitude; 1-5 concentric circles with primary color and identical pattern is placed on the test board and a normal coordinate is on the pattern; the said cervical locating device is a stand locating device in which the height can be adjusted, the pattern comprising every circle on the test board is squares with different light and shade degrees, and between the horizontal line of sight of the vision of the conner and the line of sight of the conner observing the concentric center on the test board is an included angle and is a circular orbit. When the test carriage is driven and the test carriage uninterruptedly does out and back movement in front of the test board, the conner will see the square on the test board doing anticlockwise rotation or clockwise rotation along the center of circle on the circumference.

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
