Arizona State University engineers are working on technological advances that promise to help enhance infrared photodetection used in sophisticated weapons and surveillance system, industrial and home security systems, medical diagnostics and night vision equipment for law enforcement and driving safety.
Infrared photodetection can be done more effectively by using certain materials arranged in specific patterns in atomic-scale structures. Crystals are formed in multiple ultrathin layers of the materials that are only several nanometers thick. These layered structures are then combined to form what are termed “superlattices.” The unique property of the superlattices is that their detection wavelengths can be broadly tuned by changing the design and composition of the layered structures.
Also: A miniaturized airborne imaging central server system include NASA's infrared photodetector imager.
