We report an on-chip, acousto-optic beam steering technique that uses only a single gigahertz acoustic transducer to steer light beams into free space. Exploiting the physics of Brillouin scattering, where beams steered at different angles are labeled with unique frequency shifts, this technique uses a single coherent receiver to resolve an object’s angular position in the frequency domain and enables frequency-angular resolving (FAR) LiDAR.
