12 December 1978 Cross Coherent Processing For Spatial Spectral Interferometry
Author Affiliations +
This paper reviews the concept of a spatial spectral interferometer which measures object functions to fine spatial and fine spectral resolutions, using an aperture typically two orders of magnitude smaller than ordinarily expected, while the number of detectors used is one order of magnitude less than ordinarily expected. The modulation of the component spatial frequency signals is described. It is then shown that a sparse detector array with spacings larger than the apparent Nyquist limit can be used to reconstruct the image with the alias spectra cancelled.
