Currently, all available detectors for detecting long wave infrared (LWIR) light at room temperature operate on amplitude modulation (AM) and are limited in performance by AM noises, including Johnson noise, shot noise, and background fluctuation noise. Researchers at the University of Central Florida have introduced a frequency modulation (FM)-based detection technique , which offers inherent robustness against different types of AM noises. The FM-based approach yields an outstanding room temperature noise equivalent power (NEP), response time, and detectivity (D*). According to the researchers this result promises a novel uncooled LWIR detection scheme that is highly sensitive, low-cost can be easily integrated with electronic readout circuitry, without the need for complex hybridization… read more.
