Temporal resolution (TR) refers to the
precision of a
measurement with respect to
time. Often there is a tradeoff between temporal resolution of a measurement and its
spatial resolution. In some contexts such as
particle physics, this trade-off can be attributed to the finite
speed of light and the fact that it takes a certain period of time for the
photons carrying information to reach the observer. In this time, the system might have undergone changes itself. Thus, the longer the light has to travel the lower is the temporal resolution.
