  • Publication number: 20220206146
    Abstract: We disclose a method of measuring a distance to or from a target, the method comprising: operating an emitter to generate a first pulsed signal and a second pulsed signal in a field of view of the emitter in which a target may be present, the first pulsed signal having a first pulse frequency and the second pulsed signal having a second pulse frequency, the first pulse frequency being different from the second pulse frequency; operating a detector to detect signals for a pre-determined duration after said first pulsed signal is generated and for a pre-determined duration after said second pulsed signal is generated; storing said detected signals in a memory spanning a period of the first pulsed signal and a period of the second pulsed signal, respectively; using the detected signals to identify a portion of the first pulsed signal reflected by the target and a portion of the second pulsed signal reflected by the target; determining a first virtual distance based on a difference between a reference signal and

  • Publication number: 20220003865
    Abstract: An apparatus includes a time-of-flight (TOF) sensor system that has an illuminator operable to emit pulses of light toward an object outside the apparatus. The illuminator is operable in a first mode in which the illuminator emits pulses having a first width and a second mode in which the illuminator emits pulses having a second width longer than the first width. The TOF sensor system further includes a photodetector operable to detect light produced by the illuminator and reflected by the object back toward the apparatus. An electronic control device is operable to control emission of light by the illuminator and is operable to estimate a distance to the object based on a time elapsed between an emission of one or more of the pulses by the illuminator and detection of the reflected light by the photodetector.

  • Publication number: 20210156976
    Abstract: A method of using an optical TOF module to determine distance to an object. The method includes acquiring signals in the TOF module indicative of distance to the object, using a first algorithm to provide an output indicative of the distance to the object based on the acquired signals, using at least one second different algorithm to provide an output indicative of the distance to the object based on the acquired signals, and combining the outputs of the first and at least one second algorithms to obtain an improved estimate of the distance to the object. In some implementations, each of the first and at least one second algorithms further provides an output representing a respective confidence level indicative of how accurately distance to the object has been extracted by the particular algorithm.

  • Patent number: 10705192
    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.

  • Patent number: 10578739
    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.

  • Publication number: 20170153107
    Abstract: This disclosure describes optoelectronic devices that include an event-driven photo-array and methods for using the same. The methods include capturing output signals over a particular illumination time via a change-detection circuit. In some instances, a threshold intensity change can trigger the change-detection circuit. In some instances, an active illumination from an illumination module may produce the threshold intensity change. Output signals may be used to generate distance data. In some instances, the output signals may be substantially free from noise due to background light.
