A spectrum Fourier processor comprising, an input for receiving light from a light source, an output, an optical splitter for receiving light from an input source and splitting the light into two coherent sources, means for focusing the interference pattern of light produced by the two sources such that the path difference from each source at a plane increases linearly along a principal axis, such that a Fourier plane is created the intensity distribution of which is the inverse Fourier transform of the spectra of the input source, and means for focusing light from the Fourier plane to the output. |
