摘要
A numerical reconstruction technique employing the angular multiplexing and de-multiplexing by means of the Gabor wavelet transform (GWT) in digital holography is described. The single synthetic digital hologram of angular multiplexing is obtained by encoding the information corresponding to more than one carrier frequency, or by adding the rotated holograms recorded in turn during the dynamic course numerically. The de-multiplexing is performed by employing the GWT with multiple ridges and multiple peaks for the analysis to reconstruct each object wave front according to the respective rotated hologram. The results of the simulation and experiments show the feasibility and validity of the technique.
