Optical illusion
Stereoscopy is a technique that allows to create the illusion of depth in a photograph or movie, by presenting to each eye slightly different images, as it happens during the normal vision of the eye when seeing reality. It was invented by Charles Wheatstone in 1840.
The discovery of (566) Stereoskopia clashed with the use of astronomical photography to discovery asteroids. It is part of the group of Gestalt asteroids, which were discovered at the beginning of the 20th century.
(566) Stereoskopia is related with the searching of differences between two almost identical images (21:11 resonance with Jupiter; 7:12 resonance with Vesta).
