Time-resolved measurements

Definition

Time-resolved measurements are techniques that capture and analyze transient phenomena in a system by recording data at specific intervals over time. This method is crucial in understanding dynamic processes, especially in complex environments like turbulence, where changes can happen rapidly and unpredictably. By tracking how parameters evolve over time, researchers can better comprehend the behavior of systems influenced by strong turbulence and plasma dynamics.
