DEFINITION

Classification: 359/298

Light wave directional modulation (e.g., deflection or scanning is representative of the modulating signal):

(under subclass 237) Subject matter wherein the relative spatial orientation of a light wave exiting a device is

changed in accordance with a varying signal of any energy form (i.e., modulating signal) applied to the device.

(1) Note. Optical directional modulation occuring exclusively inside of a waveguide is classified in Class 385.
