Stereoscope   Listen
noun
Stereoscope  n.  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. Note: 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.

... the two retinae there is then a relative retardation of half a period. This may be seen by means of a stereoscope, carrying, instead of stereo-photographs, incised plates through which we look at light. The design consists of two slanting cuts at a suitable distance from each other. One cut, R, slants to the right, and the other, L, to the left (see fig. 111). When ...

... friction. There is, doubtless, a consummate power of annotation that anticipates difficulties, and clears away haze, without distracting the mind. There is also an art of bringing out relief by an accompaniment, like the two images of the stereoscope. This is most likely to arise through a living teacher or commentator, who, by his tones and emphasis, as well as by his very guarded and reserved additions, can make the meaning of the author take shape ...
