DEFINITION

Classification: 359/462

STEREOSCOPIC:

(under the class definition) Subject matter comprising (1) a separate optical system for each eye of one person, which are looking at a common object, for producing separate visual records containing information from the two different points of view relative to that object, or (2) the stereoscopic record itself, or (3) the devices for viewing such records.

(1) Note. This subclass takes optical systems of stereo projectors and cameras which are not sufficient to constitute a complete projector or camera.
