Abstract
A pyrometer having at least two detectors and at least two band-pass filters near each to limit the detectable wavelength band emitted by an object, and a device to exchange their filters to eliminate detector output ratio errors. The detector output ratio is then used to derive the color temperature of the object, which may have fast changes in emission intensity output.
