Abstract
A time measurement device for calculating a time from an input of a first trigger signal to an input of a second trigger signal as a measured time includes a start gate configured to generate a start signal, a stop gate configured to generate a stop signal, a TDC circuit configured to generate a digital code corresponding to the time from an input of a start signal to an input of a stop signal, a delay circuit configured to delay an input of at least one of the start signal and the stop signal to the TDC circuit by a predetermined delay time, and a control unit configured to calculate a measured time on the basis of a plurality of digital codes generated by the TDC circuit, wherein the time delay unit selects at least two delay times.
