Abstract : Fractional Brownian motion (fBm) is the proper model for spatial noise. The noise on infrared arrays has both a temporal and a spatial component. Spatial noise (pixel-to-pixel variation) manifests itself across the array as a nonuniform response by the individual detectors to a uniform illumination. Temporal noise is observed by sampling the time series response from a single pixel. In this report the pixel responses from an indium antimonide (InSb) staring array are analyzed for their 1/f characteristics.
