ABSTRACT:
A method for remotely measuring the temperature of a target maintained at a first relatively low temperature while at the same time the target is heated by thermal radiation from a source spaced from the target and maintained at a second relatively high temperature which employs a two wavelength radiometer and a computer. First and second wavelengths are selected for use. The second wavelength is shorter than the first wavelength, both source and target exhibiting appreciable radiation at the first wavelength, the source emitting appreciable radiation while the target emits essentially no radiation at the second wavelength. The radiation of the source at the first wavelength and at the second wavelength are measured. These two source radiation measurements are stored in the computer. The radiation of the target at the first wavelength and at the second wavelength are measured. These two target radiation measurements are stored in the computer. These stored measurements in the computer are used to calculate the temperature of the target.
