DEVICE AND METHOD FOR MEASURING TIME INFORMATION OF PHOTON

WIPO Patent Application WO/2018/090901

A1

Provided in the present invention are a device and method for measuring time information of a photon. The device comprises a current detection circuit and a processing circuit, wherein the current detection circuit is used to be connected to a photoelectric sensor to detect an initial signal output by the photoelectric sensor and generate a corresponding detection signal; an input end of the processing circuit is connected to an output end of the current detection circuit; and the processing circuit is used for determining the arrival time of a high-energy photon detected by the photoelectric sensor according to the detection signal, estimating the time drift according to the detection signal, and correcting the arrival time based on the time drift. According to the device and method in an embodiment of the present invention, estimating the time drift and correcting the arrival time based on the time drift can correct a time measurement error brought about by a dark event, and simply and conveniently obtain a time measurement result with high accuracy.
