detection efficiency

Detection efficiency refers to the ability of a system or device to accurately identify or detect a specific target or event when it occurs. It is usually expressed as a percentage, indicating how often the detector successfully recognizes the event out of all the times it actually happens. For example, if a sensor detects 80 out of 100 passing objects, its detection efficiency is 80%. High detection efficiency means the system reliably identifies most events, whereas lower efficiency indicates some events are missed. This measure helps evaluate and improve the performance of detection devices across various applications.
