ABSTRACT:
An optical architecture enabling the intercorrelation of two instantaneous wideband temporal signals. The beam coming from a monomode laser is used to obtain two carriers (W1, W2) for signals R(t) and S(t) by the use of, for example, integrated optical modulators (mod1, mod2). These two carriers have orthogonal polarizations and are distributed in a 2D structure comprising spatial light modulators as well as polarization separator elements. P.times.P independent channels (Cl to Cn) are thus formed. Their detection on a matrix of photodetectors (modl to modn) makes it possible to obtain, on each of them, the intercorrelation signal for different delays of the signals R(t) and S(t).
