Forward looking infrared (FLIR) detector arrays generally produce spatially undersampled images because the FLIR arrays cannot be made dense enough to yield a sufficiently high spatial sampling frequency. Multi-frame techniques, such as microscanning

During the process of microscanning a controlled vibrating mirror typically is used to produce subpixel shifts in a sequence of forward-looking infrared (FLIR) images. If the FLIR is mounted on a moving platform, such as an aircraft, uncontrolled ran

A Kalman filter is developed to estimate the temporal drift in the gain and the offset of detectors in focal-plane array sensors from scene data. The novelty of this approach is that the gain and the offset are modeled by random sequences (state vari

It is well known that non-uniformity noise in focal-plane array (FPA) sensors, which is due to the pixel-to-pixel variation in the detectors' responses, can considerably degrade the quality of images since it results in a fixed pattern that is superi

We describe a new, to our knowledge, scene-based nonuniformity correction algorithm for array detectors. The algorithm relies on the ability to register a sequence of observed frames in the presence of the fixed-pattern noise caused by pixel-to-pixel

A statistical algorithm has been developed to compensate for the fixed-pattern noise associated with spatial nonuniformity and temporal drift in the response of focal-plane array infrared imaging systems. The algorithm uses initial scene data to gene

Laboratory imaging performance tests were conducted on two Rome Air Development Center (RADC) 160x244 Platinum Silicide (PtSi) Sensors. Both cameras were tested using their RS-170 analog composite video outputs. Digital posts were not available for b

Calibrated thermal imagers are being used more frequently than non-imaging radiometers to gather target and background infrared signature data. Current radiometric calibration guidelines should be expanded to include tests specifically designed for i
