A method of reconstructing positive and negative images simultaneously from the same dc-removed coaxial Fourier hologram with the same reference pattern is presented. The simultaneous reconstruction is possible by making the polarization of the additional dc component of the signal beam perpendicular to the polarization of the reconstructed signal beam, in which separately detected s- and p-polarization components create contrast-reversed images. This method provides an aspect of designing dc-removed coaxial holographic storage systems for realizing optical noise reduction and less consumption of dynamic range of the recording medium.
