  • Patent number: 11579291
    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.
