We study the interference between two parallel-propagating Gaussian beams,originated from the same source, as their transverse separation is tuned. Theinterference pattern as a function of such separation lead us to determine thespatial coherence length of the original beam, in a similar way that aMichelson-Morley interferometer can be employed to measure the temporalcoherence of a transform limited pulse. Moreover, performing a Fouriertransform of the two-beam transverse plane, we observe an intensity modulationin the transverse momentum variable. This observation resembles the Alford andGold Effect reported in time and frequency variables so far.
