Principles of the off-axis holographic configuration: (a) spatial carrier frequency is induced by the off-axis angle of the reference wave with respect to the system’s optical axis; and (b) four terms in the spectrum of the hologram that consists of two autocorrelation terms T1 and T2 and two cross-correlation terms T3 and T4. The bandwidths of the cross-correlation terms are half the bandwidth of autocorrelation terms.
