DETECTION BEYOND THE STANDARD RADIATION NOISE LIMIT USING SPECTRALLY SELECTIVE ABSORPTION
摘要
High sensitivity thermal detectors that perform beyond the blackbody radiation noise limit are described. Thermal detectors, as described herein, use spectrally selective materials that absorb strongly in the wavelength region of the desired signal but only weakly or not at all in the primary thermal emission band. Exemplary devices that can be made in accordance with the present invention include microbolometers containing semiconductors that absorb in the MWIR and/or THz range but not the LWIR.
