(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.

Stereoscopy
Definition:
(n.) The art or science of using the stereoscope, or of constructing the instrument or the views used with it.
Example Sentences:
