Automated system for determining minimum resolvable temperature differences

摘要

An automated system determines the minimum resolvable temperature difference of a thermal imager with respect to a background scene. The system comprises: a) a thermal energy for generating thermal signals; b) at least one pattern mask for transforming the thermal signals into thermal image signals; c) a thermal imager for detecting and transforming the thermal image signals into transformed signals; and d) a computer for determining the minimum resolvable temperature difference of the thermal imager using the transformed signals. A display coupled to the computer may be used to present the minimum resolvable temperature difference in human readable form.
