Class Information
Number: 359/618
Name: Optical: systems and elements > Single channel simultaneously to or from plural channels (e.g., light dividing, combining, or plural image forming, etc.)
Description: 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.
