Spectrally tunable quantum dot infrared detectors: Implementation of an algorithm-based spectrometer

摘要

Panchromatic (or wideband) infrared (IR) imagers enable dayight surveillance, imaging through smoke, identification of targets as well as mapping of material compositions. The signals, covering an IR wavelength range of 7–14µm, usually referred to as the long wave IR (LWIR) band, are collected by a focal plane array (FPA) and processed into a greyscale image on video screen.
