dc.description.abstractThe principle of an optical computer for the measurement of two‐dimensional spectral and cross‐spectral densities is described. The performance of one of the experimental arrangements is checked by measuring the spectral densities of a simple two‐dimensional function. The apparatus may be used to compute the Fourier transform of a two‐dimensional function.en_US

dc.identifier.citedreferenceIn order to include functions with periodic or almost periodic components (line spectrum) it is necessary to use Fourier‐Stieltjes integrals, which add nothing new. The almost periodic components can be handled in a manner similar to that given above.en_US
