Paper Abstract

The use of focal plane arrays (FPAs) in infrared imaging systems is becoming increasingly important, but in the long wave infrared the number of detector elements in the array is limited by the current state of technology and this in turn restricts the available spatial resolution or field of view. This paper describes an image processing scheme which is able to interpolate and enhance an image in a unified moving window operation. The image is first expanded to the required size by pixel replication and then processed so that the resulting spectrum approximates to that of the original scene. A numerical method has been developed to calculate the interpolator and its use has been demonstrated in a computer simulation.
