“…In digital holography, methods based on various phase-shifting techniques that compute complex holograms have been reported recently [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. These complex holograms record wavefront information of the optical field propagated from an object under measurement.…”

A signal-processing method is proposed in the fully interferometric three-dimensional (3D) imaging spectrometry. This processing computes a 3D interferogram, in which recorded fringe patterns do not directly reflect wavefront forms propagated from a polychromatic light source under measurement. This paper presents a procedure for signal processing including a synthesis of the 3D interferogram and retrieval of a set of spectral components of 3D images. We demonstrate retrieving 3D images for spectral components of two planar light sources by means of the proposed method. The procedure to synthesize the 3D interferogram in this method suggests the possibility of direct measurement of the 3D interferogram.

“…An extension of this method [3] involves altering the phase of the reference beam in order to extract the holographic data in a method akin to that used in phase-shifting DH [4]. Under specific conditions, the transport of intensity equation (TIE) [5,6] can be applied to in-line DH to minimize the effects due to the twin image.…”

“…However, this method is limited to an object which has a uniform intensity distribution. Situ [8] reported a method which records four holograms from two recording planes. This method still requires a phase delay of reference beams during measurements, and it has a singularity problem.…”

A new two step on-axis digital holography (DH) is proposed without any assumptions, phase shifting, or complicated optical components. A dual-channel Mach-Zehnder interferometer was employed. Using that setup, the object field can be reconstructed requiring only two step measurements. To eliminate position difference between two charge-coupled device (CCD) cameras, a matched filter algorithm was used. Experimental results are compared to those of the traditional phase shifting technique. The proposed approach can also be applied to single-exposure on-axis DH for real time measurement.
