Configurable light emission by selective beam-sweeping

An opto-electronic system comprising:

• a laser operable to produce a laser beam;
• an optical element comprising two or more beam-shaping portions, each of the two or more beam-shaping portions having a different optical property;
• a beam deflector arranged to sweep the laser beam across the optical element to produce output light;
• and
• electronics communicatively coupled with the laser, the beam deflector, or both the laser and the beam deflector, wherein the electronics are configured to cause selective impingement of the laser beam onto a proper subset of the two or more beam-shaping portions of the optical element to modify one or more optical parameters of the output light, and
• wherein the electronics are configured to cause the laser beam to sweep along at least one continuous path on the proper subset of the two or more beam-shaping portions.
