Abstract
The edge response is one of many techniques used to calculate the MTF (Modulation Transfer Function) of an imaging system. The MTF can be used to calculate the MRTD function (Minimal Resolvable Temperature Difference) for thermal imagers or the MRC (Minimal Resolvable Contrast) function for visible image systems. Most of the conventional techniques used to calculate the MRTD or MRC functions are time consuming and can be influenced by the subjectivity of the operator. A comparison of conventional MRTD measurements for more than 300 systems is compared with the MRTD function derived using the edge response technique.
