Fractional Brownian Motion, Wavelets, and Infrared Detector Noise

摘要

Fractional Brownian motion (fBm) is the proper model for spatial noise. The noiseon 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 antiomonide (InSb) staring array are analyzed for their 1/f characteristics....
