<title>Comparison of detected contrast measured with thermal and quantum detectors</title>

Abstract

We compare the detected contrast measured with a quantum and a modern, uncooled, thermal detectors, including the previously neglected term due to the change in the scene emissivity. For earth-based remote monitoring of room- temperature processes, the contrast detection using the quantum detector is better than that using the thermal one, even in the case that the contrast arises solely due to the emissivity changes.
