Abstract

The invention discloses a demonstration device for generating Poggendorff illusion, comprising a test board, a demonstration module and a laser. A parallel line set formed by four to six inclined line segments is arranged at the right lower part of the front surface of the test board; the demonstration module can be fixed at the left upper part of the test board, and the angle and the up-and-down position of the demonstration module can be regulated to enable the demonstration module to be arranged in the same line with any one line segment in the parallel line set; and the laser is fixed at the front end of the demonstration module. When the demonstration device is used, the front surface of the test board is displayed to an observer, and the angle and the up-and-down position of the demonstration module are regulated to enable the observer to feel and determine which line segment in the parallel line set at the right lower part is in the same line with the demonstration module; and the laser is started, the observer observes that lasers passes through the line to verify a fact.

Description

1. Technical field

[0001] The invention relates to a demonstration device and a demonstration method for demonstrating optical visual effects, belonging to the technical field of experimental demonstration devices. 2. Background technology

[0002] British visual scientist Al Seckel (Al Seckel) reported a visual picture of "Porgendorf Optical Illusion" in "The Art Of Optical Illusions". The picture is composed of a group of parallel lines and a line segment. The line segment is on the extension line of one of the parallel lines. When observing the picture with concentrated eyes, it is difficult to judge which parallel line is on the same line. The above-mentioned research results are very useful in demonstration experiments for college and middle school students, or in science popularization work in popular science publicity and education departments. When demonstrating the above results, on the one hand, the observer first judges which parallel line the line segment is on ...

Examples

Embodiment

[0014] Embodiment: the structure of the present invention is as figure 1 , as shown in Figure 2, consists of a test board 1, a demonstration module 3 and a laser 4, the lower right part of the front of the test board 1 is provided with a parallel line group 2 composed of 4-6 inclined line segments, and the demonstration module 3 can be fixed on The upper left part of the test board 1 can adjust the angle and up-and-down position of the demonstration module 3 so that it is on a straight line with any line segment in the parallel line group 2 . The laser 4 is fixed on the front end of the demonstration module.

[0015] The test board 1 is made of iron material, and the background color of the front is white.

[0016] The line segments in the parallel line group 2 have a certain width, and each line segment is the same, and the color is black.

[0017] A magnet is installed on the back of the demonstration module 3, the module has the same width as the line segment of the paral...
