Abstract: A method for fast reconstruction of off-axis digital holograms
based on digital multiplexing algorithm is proposed. Instead of the existed
angular multiplexing (AM), the new method utilizes a spatial multiplexing
(SM) algorithm, in which four off-axis holograms recorded in sequence are
synthesized into one SM function through multiplying each hologram with
a tilted plane wave and then adding them up. In comparison with the
conventional methods, the SM algorithm simplifies two-dimensional (2-D)
Fourier transforms (FTs) of four N*N arrays into a 1.25-D FTs of one N*N
arrays. Experimental results demonstrate that, using the SM algorithm, the
computational efficiency can be improved and the reconstructed wavefronts
keep the same quality as those retrieved based on the existed AM method.
This algorithm may be useful in design of a fast preview system of dynamic
wavefront imaging in digital holography.
