摘要： A time measurement apparatus 10 includes a TAC circuit 12, a measurement gate 11, a control unit 14 for setting a gate dead time, which is a time during which the measurement gate 11 is set to be in the second state, in the measurement gate 11, and the control unit 14 for deriving and outputting time information related to the detection signal based on a measurement signal output from the TAC circuit 12, and the control unit 14 functioning as a setting unit sets a time, which is an integral multiple of a repetition period of fluorescence detected by the detector 4 and is longer than a dead time of the TAC circuit 12 itself, in the measurement gate 11 as a gate dead time.

摘要： A time measuring apparatus 10 includes a digital counter 20 that outputs a count signal in response to a clock signal, a plurality of TAC circuits 12 (TAC circuits 12a to 12j) to which a detection signal detected by a detector 4 and a clock signal are input and which output measurement signals corresponding to a time between the detection signal and the clock signal, a control unit 14 that derives and outputs time information related to the detection signal based on the count signal output from the digital counter 20 and the measurement signals output from the TAC circuits 12, and a measurement gate 11 that switches between the TAC circuits 12 to which the detection signal is input, in consideration of dead times of the TAC circuits 12.
