Figure 1

Comparison of the spatial frequency domain of 6PH to standard off-axis holography. (a) Standard off-axis holography, with a single CC term and corresponding complex conjugate term, designated as CC1 and CC1*. (b) Six-pack hologram, with six CC terms and matching complex conjugate terms, thereby containing six times more data per camera exposure in comparison to (a). (c) Simplified diagram of a 6PH system. CC, cross-correlation term; DC, autocorrelation term.
