“…Alternatively, the multiplexing can be performed digitally [16][17][18][19][20][21][22][23], by positioning the wave front matrix in the SFD matrix without overlap to generate the multiplexed hologram matrix. Multiplexing is useful for various applications, with focus on acquisition of fast dynamics using optical multiplexing [6][7][8][9][10][11][12][13][14][15][16], as well as for speeding up hologram reconstruction [17][18][19][20][21] and for compression and storage of holographic data [22,23] using digital multiplexing. Digital multiplexing of hundreds of computer generated holograms can also be performed, e.g., for beam shaping [24]; however, in this case, the input holograms are not acquired optically first, but rather generated digitally.…”
