Title:
DISTANCE SENSING DEVICE AND SENSING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/231314
Kind Code:
A1
Abstract:
A distance sensing device and a sensing method thereof. The method comprises: providing distance sensing light to a distance sensing target to generate reflected light (S602); providing a collapse bias voltage (S604); counting the number of times of collapse of an optical sensing diode according to an optical sensing signal generated by the optical sensing diode by sensing the reflected light during receiving the collapse bias voltage, so as to generate a count value (S606); and determining the distance between the distance sensing device and the distance sensing target according to the count value (S608).
