Abstract

The invention discloses a length visual illusion instrument. The length visual illusion instrument comprises a bottom plate, and a first light emitting line segment, a second light emitting line segment, a first light emitting arrow, a second light emitting arrow, a third light emitting arrow, a fourth light emitting arrow, a first miniature laser, a second miniature laser and three power switches which are fixed on the bottom plate, wherein the first light emitting line segment and the second light emitting line segment are parallel to each other and are equal to each other in length, width and height; the head parts of the first light emitting arrow and the second light emitting arrow are propped against the two ends of the first light emitting line segment respectively and face outwards along the two ends of the first light emitting line segment; the head parts of the third light emitting arrow and the fourth light emitting arrow are propped against the two ends of the second light emitting line segment respectively and face inwards along the two ends of the second light emitting line segment; the heights of the first miniature laser and the second miniature laser are equal to those of the two ends of the first light emitting line segment and the second light emitting line segment respectively. The length visual illusion instrument facilitates demonstration of Muller-Lyer visual illusion and illusion discrimination.

Description

technical field [0001] The invention belongs to the technical field of experimental demonstration devices, and relates to a demonstration device for optical illusion effects, in particular to a length optical illusion apparatus. Background technique [0002] Optical illusions are erroneous judgments and perceptions based on empirical or improper reference when people observe certain objects. There are many types of optical illusions, such as color optical illusions, motion optical illusions, geometric optical illusions, etc. Among them, the most common and widely used is the geometric optical illusion. Optical illusions have a wide range of applications in physics, physiology, architectural design, product design, and traffic safety. Designing an optical illusion demonstration device is conducive to enriching the content of popular science activities and stimulating students' interest in exploring scientific secrets. [0003] The Muller--Lyer optical illusion is a typical...
