    Abstract: Optoelectronic apparatus includes an array of emitters configured to emit respective beams of optical radiation. A steering module is mounted to intercept the emitted beams and includes an optical substrate and an active diffraction grating, which is fixed to the optical substrate and has a pitch that varies in response to an electrical signal applied thereto, so as to deflect the beams of optical radiation by a variable angle dependent on the pitch. An optical metasurface is disposed on the optical substrate and configured to collimate the beams of optical radiation so that the beams form a pattern of spots on a target scene. A controller is coupled to vary the electrical signal applied to the active diffractive grating so as to shift the pattern of spots across the target scene.
