Temporal resolution

Definition

Temporal resolution refers to the ability of a system to capture changes in a signal over time, determining how accurately it can resolve events that occur at different times. In imaging systems, higher temporal resolution allows for the observation of faster processes and dynamics, which is crucial in various applications such as spectroscopy and computed tomography.
