Abstract

Although minimum resolvable temperature difference (MRTD) measurements of forward looking infrared (FLIR) systems have been around for a long time, there is still a lot of confusion and misunderstanding about the measurement techniques. C2NVEO has been performing the measurement since the middle 1970s in its image evaluation facility (IEF). The IEF is generally considered to be the standard of the free world for FLIR measurements. This paper provides a basic understanding of the measurement state-of-the-art of MRTD for first- and second-generation FLIR systems. Concepts and theory behind the measurement are addressed and equipment requirements as well as observer training are reviewed. A discussion of the challenges of evaluating new systems such as staring arrays and second-generation digital FLIRs and the requirements for both horizontal and vertical MRTD measurements is also provided. A discussion of effects at automating the measurement is provided.
