Dynamic range

From Online Dictionary of Crystallography

Plage dynamique (Fr). Dynamikumfang (Ge). Gamma dinamica (It). ダイナミックレンジ (Ja). Динамический диапазон (Ru). Rango dinámico (Sp).

The dynamic range of a detector may be defined as the range between the smallest detectable photon count rates (determined by inherent detector noise such as readout and dark noise) to the largest acceptable photon count rates (determined by the dead time).
