Abstract
We report on product maturation of small pixel high definition high charge capacity 2.4 Mpixel MWIR Infrared Focal Plane Arrays. This high definition (HD) FPA utilizes a small 5 um pitch pixel size which enables near Nyquist limited sampling with by the optical system of many IR lenses. These smaller sub diffraction pitch pixels enable improved sensitivity and resolution resulting in clear, crisp high contrast imaging with excellent IFOVs even with small focal length lenses. The small pixel IR sensor allows the designer to trade off field of view, MTF, optics F/# to obtain a more compact and high performance IR sensor. This enables lower size, power and weight reductions of the entire IR Sensor System. The highly sensitive MWIR small pixel HD FPA has the capability to detect dimmer signals at longer ranges than previously demonstrated.
