Abstract: The present disclosure describes intelligent illumination systems that use modulated light. For example, in one aspect, a method includes producing, by a light source, modulated illumination in a visible part of the spectrum, detecting three-dimensional image data based on at least a portion of the modulated light produced by the light source and reflected by a scene, and changing a characteristic of the modulated illumination based on the detected three-dimensional image data.

Abstract: The present disclosure describes optoelectronic modules that, in some implementations, address the need to combine precise measurements of scenes over a range of near and far distances. For example, an optoelectronic module can include a light emitter operable to direct modulated structured light onto a scene. The module includes an imager to receive reflected light signals from the scene. The imager includes demodulation pixels operable to provide amplitude and phase information based on the reflected light signals. Various techniques can be used to derive distance or three-dimensional information about the scene based on the signals from the pixels.
