Webster's Revised Unabridged Dictionary
    • n Stereoscope An optical instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one, through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimposed, so as to appear as one to the observer.☞ In the reflecting stereoscope, the rays from the two pictures are turned into the proper direction for stereoscopic vision by two plane mirrors set at an angle with each other, and between the pictures. In the lenticular stereoscope, the form in general use, the eyeglasses are semilenses, or marginal portions of the same convex lenses, set with their edges toward each other, so that they deflect the rays coming from the picture so as to strike the eyes as if coming direct from an intermediate point, where the two pictures are seen apparently as one.

    • n stereoscope An optical instrument illustrating the phenomena of binocularvision, and serving to produce from two nearly similar pictures of an object the effect of a single picture with the appearance of relief and solidity belonging to ordinary vision. It depends upon the fact that in ordinary vision, while the respective images of an object formed upon the retinas of the two eyes differ slightly because of the divergence of the rays from each point of the object, yet the effect upon the brain is that of a single object seen in perspective relief which the monocular image lacks. The slide of the stereoscope shows two pictures side by side taken under a small difference of angular view, each eye looking upon one picture only; thus, as in ordinary vision, two images are conveyed to the brain which unite into one, exhibiting the objects represented under a high degree of relief. A reflecting form of stereoscope was invented by Sir Charles Wheatstone in 1838. Subsequently Sir David Brewster invented the lenticular or refracting stereoscope, based on the refractive properties of semi-double-convex lenses. This is the one now in general use. There are many forms of it, one of which is shown in the figure. The action is illustrated by the diagram beneath. The light-rays from corresponding points of the two pictures P and P′ are refracted in passing through the lenses L, L′ , and their directions changed so that they now seem to the eyes E, E′ to diverge from a common point A beyond the plane of the card. By special effort a skilled observer can combine stereoscopic pictures into one without the use of the instrument, each eye being directed to one picture only and (to produce the normal stereoscopic effect) the one ou its own side; the process may be facilitated by interposing a card screen between the pictures so that, for example, the left picture is entirely cut off from the right eye, etc. If the eyes are crossed so that the right eye sees the left picture and the left eye the right only, and the images combined by special effort, the usual stereoscopic effect is reversed—a convex surface becomes concave, etc. A similar pseudoscopic result is obtained with the ordinary stereoscope if the positions of the two pictures are exchanged.

    • n Stereoscope ster′ē-ō-skōp an instrument in which each of two pictures is examined by a separate lens, and the two lenses are inclined so as to shift the images towards one another, and thus to ensure or to facilitate the blending of the two images into one, standing out in relief with solidity
