Abstract
An optical image characterizer 10 detects light energy as discrete angular orientations of a slit in a rotating spatial filter positioned at the focal plane of a Fourier transform lens, where a Fourier transform pattern of spatial frequencies of an image are formed. Detection of light energy with a small array (e.g., 16.times.16) photodetector is enhanced by splitting the beam containing the filtered light energy pattern and projecting it onto two photodetector arrays in offset, virtual juxtaposed relation to each other. Detected light intensities I at discrete angular orientations R are stored in RIXel data arrays with or without searchable flags X, such as distortion factors.
