Stereoscopy

Stereoscopy, stereoscopic imaging or 3-D (three-dimensional) imaging is any technique capable of recording 3 dimensional visual information or creating the illusion of depth in an image. Often the illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. Many 3D Displays use this method to convey images. It was first invented by Sir Charles Wheatstone in 1838. Stereoscopy is used in photogrammetry and also for entertainment through the production of stereograms. Stereoscopy is useful in viewing images rendered from large multi-dimensional data sets such as are produced by experimental data. Complex three-dimensional objects such as molecular models that exist only in computer data sets may also be rendered using stereoscopy as an aid to creating medications. Photographically created digitized three dimensional models are also used in various industrial and medical applications such as CAD/CAM.

Traditional stereoscopic photography consists of creating a 3-D illusion starting from a pair of 2-D images. The easiest way to create depth perception in the brain is to provide to the eyes of the viewer two different images, representing two perspectives of the same object, with a minor deviation similar to the perspectives that both eyes naturally receive in binocular vision. Modern industrial three dimensional photography may use laser or other advanced techniques to detect and record 3 dimensional information.
