Stereoscopy
Definition:
(n.) The art or science of using the stereoscope, or of constructing the instrument or the views used with it.
Example Sentences:
(1) Easy detection of temporal variations of tissue configurations within the optic disc or other structures is possible by means of stereoscopy: Stereochronoscopy.
(2) The three-dimensional structure of the sarcoplasmic reticulum (SR) of the twitch and slow tonic fibers in the skeletal muscles of the chicken and frog was examined using a modified Golgi method combined with stereoscopy employing high-voltage electron microscopy.

(8) A complex method for measuring vessels of the lungs is suggested; the method includes a number of successive procedures: contrasting of vessels under physiological pressure, stereoscopy of the preparation of the lung in a non-atelectatic and non-fixed state and obtaining of stereopaired angiograms, marking the levels of branching of vessels and determination of their lumen by means of stereocomparator, fixation of the lung, spot cutting and morphometry of the wall of the same segments of the lung vessels.
(9) Important details were transferred from each half of the stereo pairs into transparent sheets; this improved stereoscopy and made it easier to appreciate the relationship to the tracheal bifurcation.
(10) Dynamic stereoscopy led to very precise fine spatial orientation, but it failed with average velocities; dynamic parallactoscopy had coarser visual powers, but it was relatively independent of speed and thus rendered essentially better spatial orientation possible at rapid velocities.
(11) We review herein, and demonstrate for the reader whenever possible, certain key perceptual properties of the stereoscopic event of which any general theory must take account: vector stereoscopy and the neural grid, depth in empty visual fields, the relationship between stereoscopic and cognitive contours, stereoscopic contour formation in the presence of blur (thus, at low levels of central visual acuity), the phenomenon of cortical locking and of neural grid evocation in the presence of either peripheral or central rivalry, certain unusual ranges of figural mismatch and the concept of the horopter in relation to modern single cell electroneurophysiology in animals and to the constancy of visual directions.
