How Does a Pseudoscope Work?

The AstroMedia Pseudoscope has mirrors that swap the two images the eyes perceive. It also has one innovation that no other pseudoscope has had before: the two large mirrors can swivel on axles and therefore make it possible to adjust the focus for objects at different distances.

Who invented the pseudoscope?

The pseudoscope is a device that plays a trick on the eyes, switching the perception of near and far by reversing stereoscopic vision. It was invented by the great Victorian-era scientist Charles Wheatstone, and M.C. Escher used one to help create some of his famous perspective- bending illustrations.

What is pseudoscopic vision?

Basically, pseudoscopic vision is three-dimensional vision in reverse. For example, in aerial photography, swimming pools appear to look like buildings and buildings appear to look like swimming pools. In red and green plotters like the Kelsh and Multiplex this is achieved by reversing the lenses on the 3D glasses.
