Abstract

The minimum resolvable temperature (MRT) is an important thermal imager performance measure. A desire to automate this subjective test has several motivations: no trained observer would be required, the test would have better repeatability between different observers and facilities, and the test flow of an automated computer controlled test station would not be interrupted by operator inputs. A figure of merit calculated from digitized video frames at multiple blackbody temperatures was related to a simultaneous subjective measurement using a linear scale factor. A measurement data base was compiled which gives a surprisingly good correspondence to subjective measurements over a wide range of conditions.
