Abstract

The noise equivalent temperature difference (NETD) of forward looking infrared (FLIR) systems is a widely used performance parameter that characterizes the sensitivity of thermal imaging sensors. Although this parameter has been used for many years, there has always been some confusion and misunderstanding about how to measure it. Differences in opinion on how this measurement should be made can cause substantial variations in reported values of NETD measurements. It is the intent of this paper to clearly describe the measurement technique used at Night Vision and Electronic Sensors Directorate (NVESD).
