Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of optical illusion apparatus for demonstrating, is specially a kind of length illusion scope.
Background technology
Time in background line segment equal for some length being placed on some specific lines compositions, owing to being subject to the vision interference of background, the line segment that these length are equal looks and can seem different in size.At present, lack a kind of clear observation and differentiate the special demonstration equipment of the short-sighted illusion of this length along path.
Summary of the invention
The purpose of this utility model is a kind of length illusion scope designing the clear demonstration of a kind of energy and be conducive to illusion resolution.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: comprise base, the first luminous line segment, the second luminous line segment, the 3rd luminous line segment, the 4th luminous line segment, the first laser instrument, second laser, the 3rd laser instrument, the 4th laser instrument, described base is rectangle, the length of described first luminous line segment, the second luminous line segment, the 3rd luminous line segment, the 4th luminous line segment is equal, first luminous line segment, the second luminous line segment, the 3rd luminous line segment, the 4th luminous line segment are embedded at susceptor surface with the horizontal symmetry axis that the vertical axis of symmetry of base is line segment center, be parallel to base respectively, the distance of the first luminous line segment and the 4th luminous line segment seat horizontal symmetry axis is on earth equal, and the distance of the second luminous line segment and the 3rd luminous line segment seat horizontal symmetry axis is on earth equal, described first laser instrument and the 4th laser instrument, second laser and the 3rd laser instrument are respectively centered by the vertical axis of symmetry of base, symmetrically be distributed on the base of base, first laser instrument, second laser, 3rd laser instrument, 4th laser instrument sends laser rays A respectively, laser rays B, laser rays C, laser rays D is totally four bundle laser rays, laser rays A, laser rays B, laser rays C, laser rays D intersects at base central point (intersection point of horizontal symmetry axis and vertical axis of symmetry), laser rays A, laser rays D is respectively through the second luminous line segment, the two ends of the 3rd luminous line segment, laser rays B, laser rays C is respectively through the first luminous line segment, the two ends of the 4th luminous line segment.
