Inverse-problem based algorithm for THz off-axis digital holography reconstruction

We apply an inverse-problem-based reconstruction technique to off-axis THz digital holography. Off-axis digital holography configuration at THz regime suffers from non-ideal recording conditions due to the large wavelength. The proposed method takes into account the non-uniformity of the reference wavefront. Compared to the direct Fourier filtering reconstruction, our method reduces the standard deviation of the reconstructed phase.
