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.
