US Patent 10408922 Optoelectronic module with low- and high-power illumination modes

The present disclosure describes optoelectronic modules with low- and high-power illumination modes for distance measurements and/or multi-dimensional imaging. Various implementations are described that include low- and high-power emitters. In some instances, a low-power mode may be used to monitor a scene where object movement can activate a high-power mode. In such instances, power reduction may be achieved.
