PHOTONIC BEAM STEERING DEVICE WITH WAVELENGTH SWEEP

A beam steering system includes a light source configured to generate an optical beam at various wavelengths. An array of emitters receives the beam and selectively emits the beam. An optical device receives the beam and directs the beam into an external environment of the beam steering system. The...

Beschreibung
Zusammenfassung:	A beam steering system includes a light source configured to generate an optical beam at various wavelengths. An array of emitters receives the beam and selectively emits the beam. An optical device receives the beam and directs the beam into an external environment of the beam steering system. The beam is directed into the external environment at different angles corresponding to a location of the emitter and the wavelength of the beam. As a result, the beam steering system steers the beam for a three-dimensional scan of the external environment.
