ASTM E1543-00 Standard Test Method for Noise Equivalent Temperature Difference of Thermal Imaging Systems
standard by ASTM International, 02/10/2000
1.1 This test method covers the determination of the noise equivalent temperature difference (NETD; NE[delta]T) of thermal imaging systems of the conventional forward-looking infrared (FLIR) or other types that utilize an optical-mechanical scanner; it does not include charge-coupled devices or pyroelectric vidicons.
1.2 Parts of this test method have been formulated under the assumption of a photonic detector(s) at a standard background temperature of 295
