Optical Processing in Radon Space.
Abstract
Signals of M dimensions (M>1) can be reduced to one-dimensional data by integration over M-1 dimensions. This operation is known as the Radon transform. Many useful two-dimensional signal processing operations can be performed rapidly by first producing the one-dimensional projection data and operating on the projections with efficient one-dimensional processors, such as surface acoustic wave devices. Such operations as spectrum analysis, complex Fourier transformation, production of the Wigner distribution function, and convolution can be performed in this manner, and may be done more rapidly or more accurately than by more conventional methods. Keywords include: Optical data processing; Radon transform; Surface acoustic wave filters.
