Demonstration of megapixel dual-band QWIP focal plane array

There are many applications that require mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) dual-band focal plane arrays (FPAs). For example, a dual-band FPA camera would provide the accurate temperature of a target with unknown emissivity which is extremely important to the process of identifying objects based on their surface temperature. Dual-band infrared FPAs can also play many important roles in Earth and planetary remote sensing, astronomy, etc.
