Abstract: An optical ranging system includes a support, a light emitter mounted on the support, and a time-of-flight (“TOF”) sensor chip mounted on the support. The TOF sensor chip, for example, includes at least one main pixel and at least one reference pixel in a semiconductor substrate. A barrier that is substantially non-transparent to light emitted by the light emitter separates the at least one reference pixel from the at least one main pixel. The optical ranging system also includes features for reducing optical cross-talk between the light emitter and the pixels of the TOF sensor.

Abstract: An optoelectronic module operable to acquire distance data and spectral data includes an array of demodulation pixels and an array of spectral filters. The demodulation pixels can possess an intrinsic wavelength-dependent sensitivity, wherein the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing micro-lens array in some cases. In some cases, the intrinsic wavelength-dependent sensitivity can be offset by a combined filter array, while in other cases the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing filter array. Still in other cases, the demodulation pixels can be operable in such as to offset the intrinsic wavelength-dependent sensitivity.

Abstract: An optoelectronic module operable to collect distance data via a time-of-flight mode and a time-of-flight-triangulation mode includes an illumination assembly and an imaging assembly. The imaging assembly includes at least one demodulation pixel operable to determine distance to an object via a time-of-flight mode and a time-of-flight-triangulation mode. Multi-path distance inaccuracies can be mitigated in some implementations.

Abstract: A time of flight-based system is operable for ambient light measurements. A method of operation includes detecting, in at least one active demodulation detection pixel, a first particular wavelength and generating amplitude data of the first particular wavelength; and detecting, in at least one spurious reflection detection pixel, a second particular wavelength and generating amplitude data of the second particular wavelength. In a computational device that stores spectrum data corresponding respectively to a plurality of different ambient light source types, an ambient lighting condition is determined based on the amplitude data of the first particular wavelength, the amplitude data of the second particular wavelength and the spectrum data of a particular one of the ambient light source types associated with the amplitude data of the first particular wavelength and the amplitude data of the second particular wavelength.

Abstract: Optoelectronic modules (100) are operable to distinguish between signals indicative of reflections from an object of interest and signals indicative of a spurious reflection. Various modules are operable to recognize spurious reflections by means of dedicated spurious-reflection detection pixels (126) and, in some cases, also to compensate for errors caused by spurious reflections.

Abstract: The present disclosure describes optical imaging and optical detection modules that include sensors such as time-of-flight (TOF) sensors. Various implementations are described that, in some instances, can help reduce the amount of optical cross-talk between active detection pixels and reference pixels and/or can facilitate the ability of the sensor to determine an accurate phase difference to be used, for example, in distance calculations.
