Paper Abstract

The study presents the generating procedure of random optical signals by means of parallel beam modulation. The beam transverses a complex transmission mask. It is also presented the measuring method to determine the bi-dimensional energetic intensity distribution of the signal. By means of data got experimentally and processed on computer, some specific characteristics of optical processes can be established: mean value, dispersion and correlation function. The correlation function experimentally obtained is approximated through two known analytical functions, depending on one parameter. Finally, Fourier integrals and adjusted analytical functions allow determination of signal's spectral density.
