Temporal Resolution

Definition

Temporal resolution refers to the precision of a measurement with respect to time. In optical systems, it defines how closely events can be captured and distinguished in time, which is critical for applications that involve fast processes. High temporal resolution allows for the detection of rapid changes and dynamic phenomena, making it essential in various technologies, such as image capture and remote sensing techniques.
