What Does NEDT Stand For?

NEDT stands for Noise Equivalent Delta T

NEDT, or Noise Equivalent Delta T, is a critical measurement used in the field of thermal imaging and infrared detection, quantifying the smallest temperature difference that can be detected by a sensor amidst background noise. It reflects the sensitivity and performance of thermal cameras, indicating their capability to distinguish thermal variations in a given scene. Lower NEDT values denote higher sensitivity, enabling improved image quality and accuracy in various applications, including surveillance, search and rescue, and environmental monitoring.
