Quantum-Dot Focal Plane Array Has Two-Color Capability

Facebook X LinkedIn Email
Anne L. Fischer

Mid- (3 to 5 μm) and long-wave (8 to 12 μm) infrared focal plane arrays have found a place in numerous security and military applications that require night-vision capability. Single-color detectors have been common, but monolithic two-color devices offer several advantages, such as the ability to detect the absolute temperature map of a scene. Two-color detectors have been demonstrated using mercury cadmium telluride (MCT) and quantum-well detectors. Now a group at the University of New Mexico in Albuquerque — in collaboration with researchers from its start-up company, Zia...Read full article
