Discussed in direct relation to fractal Fourier transforms are spatial resolution and the space-bandwidth product for propagation in graded-index media. Results show how fractional Fourier transforms can be made the basis of generalized spatial filtering systems.EnglishMathematical modelsOptical data processingOptical filtersCorrelationFractional Fourier transformsSpatial filteringFourier transformsFractional Fourier transforms and their optical implementation.
