The following is an exerpt from an article prepared by Nakken. The invention of the? stereoscope in 1832 seemed to hold great promise. Here two pictures of the same subject are produced by means of two cameras spaced 6.5 cm apart, a distance equal to the average inter- pupillary separation of the eyes. These pictures, of course, are slightly different in the same way that the two images on the retinas of the eyes are slightly different from each other. , Just as a single picture viewed monocularly can be an adequate substitute for reality, so do these two pictures substitute for that which the two eyes would see in a given scene, provided of course, that the left and right eyes view only left and right pictures respec tively.
