Zusammenfassung:In some embodiments, apparatus and systems, as well as methods, may operate to receive radiation at an active detector of a pair of radiation detectors to provide a first signal proportional to an intensity of the radiation, to receive none of the radiation at a blind detector of the pair of radiation detectors to provide a second signal proportional to the reception of no radiation, and to combine the first signal and the second signal to provide an output signal representing the difference between the first signal and the second signal. The pair of radiation detectors may comprise thermopile detectors. Combination may occur via differential amplification. Additional apparatus, systems, and methods are disclosed.
