Abstract

We consider the process of recording time integrated Fourier-holograms of signals, converted by an acousto-optical modulator (AOM). The AOM is assumed to be illuminated by a narrow scanning laser beam, while the incidence angle of the reference wave is changed simultaneously. We demonstrate the possibility of uninterrupted recording of continuous information flow as an array of Fourier-holograms. It is found that the Doppler frequency bandwidth of a reference wave can be twice as less as the bandwidth of signals recorded.
