Electronics Engineer

Philip Plummer, an electronics engineer with the Air Force Research Laboratory, transfers liquid nitrogen into a container, known as a dewer, attached to infrared detectors which must be kept at temperatures as low as -80 Kelvin to reduce thermal noise in an image. The infrared camera, which contains a novel focal plane design, is being tested at AFRL at Wright Patterson Air Force Base in Dayton, Ohio, for sensitivity, operability and resolution in applications such as night time surveillance, target detection, persistent ground surveillance and air-to-air target tracking.
