What Does NETD Stand For?

NETD stands for Noise Equiv Temp Difference

NETD, or Noise Equivalent Temperature Difference, is a measurement that quantifies the smallest temperature difference that can be detected by a thermal imaging system. It is a critical performance metric that indicates the sensitivity of an infrared sensor or camera, influencing its ability to clearly resolve thermal contrasts in various applications, including surveillance, scientific research, and healthcare diagnostics. A lower NETD value signifies higher sensitivity and improved detection capabilities in thermal imaging.
