Acquisition times

Definition

Acquisition times refer to the duration required to collect terahertz images or data during the imaging process. In the context of explosives detection, minimizing acquisition times is crucial, as it directly impacts the efficiency and effectiveness of scanning for threats in various environments. Faster acquisition times enable quicker decision-making and can improve overall security operations.
