Stereoscopy

Have you ever found yourself sitting in a theater wearing goofy paper glasses designed
to make a movie appear 3D? Did you later look at the same pictures without the goofy
glasses only to discover that they were not 3D anymore? If you answered yes to either
question, then you have experienced the difference between normal and stereoscopic
images. This all deals with a modern technique called stereoscopy.

Stereoscopy or 3D imaging adds depth to images, making certain pictures appear 3D. In
order to create the illusion of depth, stereoscopy manipulates the way the eyes process
information. Because eye manipulation sounds a bit high-tech, you might think that
stereoscopy was a pretty recent innovation, but it was actually invented in 1838 by an
English physicist. As old as it is, stereoscopy is still used today for presenting
various types of images and has multiple wide-ranging applications.



This website designed is to inform interested physics students about
the ideas behind stereoscopy and how it works.
