A time-resolved measurement apparatus (100) acquires a detection timing
pulse from an output terminal (34) attached to a micro channel plate (30)
in a photomultiplier tube (14). A position-time measuring circuit (16)
generates a signal indicating the time difference between a reference
time pulse synchronized with excitation of a sample (10) and the
detection timing pulse, and feeds the signal to a data processor (18).
The data processor stores this time difference as a detection time of
light emission. The data processor corrects the detection time according
to the distance between the position at which the detection timing pulse
is generated on the micro channel plate and the output terminal. This
enhances the precision of time-resolved measurement.
