ˌorthostereoˈscopic, a.
[f. ortho- + stereoscopic a.]
Showing solid objects with their true proportions and perspective, spec. without the reversal of convexity and concavity produced in pseudoscopic instruments.
1892Jrnl. Quekett Microsc. Club V. 46 If orthostereoscopic vision is required the transposition must be corrected. 1937Jrnl. Optical Soc. Amer. XXVII. 339/2 In the x-ray clinic, orthostereoscopic radiographs help to reduce error in diagnoses. 1941R. M. Allen Photomicrogr. v. 236 It is not essential, especially for higher-power work with single objectives, that true orthostereoscopic effects be obtained. 1966H. Asher tr. Valyus's Stereoscopy ii. 94 Observation of these conditions ensures that an orthostereoscopic image is produced, i.e. one which shows a correct proportion in depth and undistorted perspective, and allows the visual fusion of the two stereograms into a single spatial percept.
Hence orthoˈstereoscope, a binocular microscope giving orthostereoscopic images; ˌorthostereoˈscopically adv., in an orthostereoscopic manner; ˌorthostereˈoscopy, the production of orthostereoscopic images.
1892Jrnl. Quekett Microsc. Club V. 52 If the two prisms were joined into one, it would..make a very efficient orthostereoscope. 1928B. J. Leggett Theory & Pract. Radiol. III. ix. 430 This process of ortho-stereoscopy has important practical bearings. 1937Jrnl. Optical Soc. Amer. XXVII. 333/2 A Greenough type microscope, if the magnification is not too high, may be built to operate orthostereoscopically for related combinations of objective and eyepiece pairs. Ibid. 339/2 Accuracy in the making of contour maps by aerial stereophotography depends upon the complete achievement of orthostereoscopy. 1966H. Asher tr. Valyus's Stereoscopy ix. 380 Only when all these conditions are observed will the primary image system ‘see’ the object orthostereoscopically. Ibid. 409 To reproduce a natural relief the conditions of orthostereoscopy must be observed. |
