Stereoscopy (pronounced: /ˌstɛriːˈɒskəpi/) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from Greek στερεός (stereos), meaning 'firm, solid', and σκοπέω (skopeō), meaning 'to look, to see'.

History

The concept of stereoscopy can be traced back to the 1830s. Sir Charles Wheatstone was one of the pioneers in this field, who introduced the stereoscope, a device for viewing a pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.

Technique

In stereoscopy, two slightly offset images are displayed separately to the left and right eye. Both images are then combined in the brain to give the perception of 3D depth. This technique is distinguished from 2D imaging, where only one image is presented, either on a screen or through a viewfinder.

Applications

Stereoscopy is used in various fields such as photography, cinematography, architecture, radiology, and more. In the field of medicine, it is used in radiology to view images in three dimensions, providing a more detailed view of the human body.
