Abstract
Dual pyrometric detectors and method measure the temperature of a remote heated object in the presence of ambient radiation. One detector measures emitted radiation from both the remote object and from the environment, and the other detector measures radiation predominantly from the environment alone. The output signals from the two detectors are processed electronically to yield the detected radiation from the remote object alone. The result can then be electronically processed to display the pyrometrically-measured temperature of the remote object.
