pseudoscope|ps-, ˈsjuːdəskəʊp|
[f. pseudo- + -scope.]
An optical instrument invented by Wheatstone, containing two reflecting prisms which can be so adjusted as to produce an apparent reversal of the convexity or concavity of an object.
1852Wheatstone Physiol. Vision §23 in Phil. Trans. 11 As this instrument conveys to the mind false perceptions of all external objects, I have called it the Pseudoscope. 1855H. Spencer Princ. Psychol. (1872) I. iii. x. 380 When looked at through the Pseudoscope, convex objects seem concave. 1879H. Grubb in Proc. Royal Dubl. Soc. 180 If we place it in a pseudoscope—i.e. an instrument which enables us to view the right picture with the left eye, and the left with the right—it stands up like a solid body, just the reverse of the effect in the stereoscope.
So pseudoscopic |-ˈskɒpɪk| a., pertaining to the pseudoscope; involving apparent reversal of convexity and concavity, or other optical illusion (hence pseudoˈscopically adv.); pseudoscopy |-ˈɒskəpɪ|, the use of the pseudoscope; the production of optical illusions such as are caused by it.
1857Grove Contrib. Sc. in Corr. Phys. Forces (1874) 444 With terrestrial objects the effect of the binocular..is in many instances pseudoscopic. 1872Contemp. Rev. XIX. 411 When we look pseudoscopically at the face of a plaster bust, or at the outside of a mask, it is only after a lengthened gaze that such ‘conversion of relief’ occurs. 1951L. P. Dudley Stereoptics i. 21 If the two components of a stereogram be transposed so that the ‘left-eye’ view is seen by the right eye, and the ‘right-eye’ view by the left eye, the result is no longer a true stereoscopic effect, but is what is termed pseudoscopy. 1960New Scientist 14 July 142/3 In 1953, when interest in 3-D had a temporary revival, I took up experiments..on a new line. These were based on the observation that ‘pseudoscopy’—that is to say, the effects of the left eye seeing what the right eye ought to have seen, and vice versa—were not at all as bad as one would expect. |
