stereopsis|stɛriː-, stɪəriːˈɒpsɪs|
[f. Gr. στερε-ός solid (see stereo-) + ὄψις power of sight.]
The ability to perceive depth and relief by stereoscopic vision.
1911Stedman Med. Dict. 826/1 Stereopsis, stereoscopic vision. 1920Arch. Opthalmol. XLIX. 64 When the facts are known it is quite possible that visual tests will not stop with measuring the acuity of each eye and the color sense, but that a certain standard of stereopsis will be required. 1961Lancet 22 July 168/2 No stereopsis has been demonstrated in any of these patients. 1972Sci. Amer. Aug. 86/3 By providing very precise localization of objects in visual space, stereopsis can be regarded as the raison d'être of binocular vision.
Hence stereˈoptic a.; stereˈoptically adv., with an appearance of depth; stereoscopically.
1931Arch. Ophthalmol. VI. 139 Stereoptic reactions of a grade above the lowest are observable in ordinary fishes, but the lowest grade is probably not represented in any surviving species. 1972Sci. Amer. Apr. 65/3 One can also feed the three-dimensional coordinates into a computer and obtain simple ball-and-stick drawings that can be viewed stereoptically, enabling one to visualize the folded chain of the protein in three dimensions. Ibid. Aug. 120/2 No one believes that the anatomical retina could possibly be given information on any large scale from the mind; there are few, if any, outgoing pathways. Therefore, Julesz conjectures, the eidetic image is formed later than the image on the retina but earlier than the stereoptic image, perhaps much earlier. 1976Billings (Montana) Gaz. 24 June 16-a/1 More pictures were taken Wednesday on Viking's fourth pass over the site, Chryse, by Viking's twin cameras. They were lined up to photograph overlapping strips which can be viewed stereoptically for a three-dimensional effect. |
