DEFINITION

Classification: 359/618

SINGLE CHANNEL SIMULTANEOUSLY TO OR FROM PLURAL CHANNELS (E.G., LIGHT DIVIDING, COMBINING, OR PLURAL IMAGE FORMING, ETC.):

(under the class definition) Subject matter wherein either (1) a single light ray is used to produce a plurality of groups of different optical axes light rays, which may have different directions or be parallel and displaced relative to one another, each containing the same information as the single light ray or (2) a single light ray is derived from a plurality of groups of light rays having different optical axes in order to include the same information contained in each of the plurality of groups of light rays.

(1) Note. This subclass includes partially transmitting reflector type beam splitters wherein each split channel contains identical information.

(2) Note. This subclass includes a system comprising a plurality of adjacent lenses which form a plurality of

similar rather than identical images as a result of parallax.
