Manufacturers and Users of the Thermal Imagers have spent very much time upon the definition and measurement of the generally accepted performance curve: MRTD (Minimum Resolvable Temperature Difference). The need for a cheap and fast, objective measurement method has considerably increased since the large scale introduction of thermal imagers. This paper contains a contribution to such a method, based upon simple targets, a CCD-camera and an IBM-PC with frame-grabber unit and fast computation algorithms
