Claim 19:
20. A depth camera assembly (DCA) comprising:
a first non-mechanical steering element configured to function as a diffraction grating that performs, within a first angular spread, diffraction of one or more optical beams emitted from an illumination source;
a second non-mechanical steering element in an optical series with the first non-mechanical steering element and separated from the first non-mechanical steering element, the second non-mechanical steering element configured to function as a deflection element that performs, within a second angular spread that is more than double relative to the first angular spread, deflection of the one or more diffracted optical beams to generate outgoing light illuminating a local area;
an imaging sensor configured to capture one or more images of the local area including reflected light composed of portions of the outgoing light reflected from one or more objects in the local area; and
a processor configured to determine depth information for the one or more objects in the local area based in part on the one or more images captured by the imaging sensor.
