Abstract
An application of infrared radiometer or IR camera has been widely spread in many industries for these twenty years, because of its convenience to use, wide measuring range by remote sensing, and visual survey due to thermal image. In this IR method it is very useful to detect invisible surface and internal flaws. Conventional IR makers are accustomed to use NETD as the resolution characteristics of IR camera, but general customers using IR camera cannot evaluate the minimum detectable size of measuring object, if they cannot evaluate MRTD. The study of the quantitative evaluation to clarify the relation between NETD and MRTD is very little. This paper represents evaluation methods of NETD and MRTD, and their quantitative relation by using collimator FLIR testing.
