TIME-OF-FLIGHT RANGING SENSOR AND TIME-OF-FLIGHT RANGING METHOD

摘要

A time-of-flight ranging sensor and a time-of-flight ranging method are provided. The time-of-flight ranging sensor includes a signal processing circuit, a light emitter, and a light sensor. The light emitter emits a pulsed light having a first polarization direction to a sensing target. The light sensor senses the pulsed light reflected by the sensing target to output a first sensing signal via a first sub-pixel repeating unit and output a second sensing signal via a second sub-pixel repeating unit to the signal processing circuit. The signal processing circuit determines a pulse signal according to the first sensing signal and the second sensing signal, and the signal processing circuit determines a depth information of the sensing target according to the pulsed light and the pulse signal.
