Experimental investigation of registration peculiarities of digital Fourier holograms in case of Nyquist frequency excess has been carried out. It has been shown, that exceeding of Nyquist frequency by carrier frequency of the hologram leads not to disappearance of the reconstructed image, but to gradual decrease of image intensity, which indicates decrease of hologram diffraction efficiency.
