ABSTRACT:
A sensor that is responsive to at least two distinct spectral bands, e.g., infrared radiation and ultraviolet or infrared and visible light makes use of the junction of a diode-based bolometer as a photocell in addition to its temperature dependence for detecting infrared radiation. More specifically the diode bolometer is arranged to work in the conventional manner, in that an electrical characteristic of the diode, e.g., the temperature dependence of its current-voltage (I-V) curve, is used as the basis for measuring temperature, and hence, infrared radiation. Additionally, the same diode may be operated as a photocell to detect radiation that is capable of interacting with the electrons in the junction of the diode. This may be achieved by detecting a change in the operating point of the diode based given its present biasing in response to noninfrared radiation incident upon the diode.
