The review of the radio pulses acousto-optical correlator allows us to create an algorithm for calculation the correlation functions on the basis of pre-calculated instantaneous spectra of correlated pulse signals and it is given its interpretation in the form of a functional scheme. The new definition of the instantaneous spectrum explaining the operation of real spectral devices: an acousto-optical spectrum analyzer of radio signals and diffraction (lattice) spectral optical analyzer was introduced. Mathematical identity complex spread functions of acousto-optic spectrum analyzer of radio signals and optical diffraction spectral analyzer allows us to put the question about the implementation of the correlation of the optical pulse signals based on diffractive optical spectral analyzers.
