“…All the measured matrix elements had similar amplitudes compared to the theoretical values, and some deviations are within reasonable bounds, which confirming the feasibility of our approach. To better demonstrate the reconstructed performance, the MSE [36] is utilized to evaluate the reconstruction quality of the method during the experiment. Table 1 represents the MSE values of the Jones matrix for the polarizers at different orientation angles, which further prove the accuracy of the polarization measurement of the system.…”

A polarization digital holography (DH) using angular multiplexing was developed for extracting the Jones matrix of anisotropy materials in one step. This technique is implemented by adopting an off-axis interferometric configuration connecting two identical CCD cameras. The combined orthogonal 45° beams is split using a nonpolarizing beam splitter to produce the sample and reference beams. Our method yields two angular-multiplexing polarization interferograms simultaneously, in which the orthogonal fringe directions for each interferogram are modulated by two self-installed retro-reflector mirrors. In this case, the spatially resolved Jones matrix parameters of the polarization-sensitive materials can be determined in one step. The basic feasibility of the scheme is verified by measuring the Jones matrices of polarizing optics, a transmitted spatial light modulator, and synthetic mica plates.

“…However, when the object shows strong phase fuctuations, the iterative process cannot converge. Wang et al [19,20] suggested a new hybrid method (IOHDH), the approximate phase distribution of the object wave from the of-axis hologram by using the constrained optimization algorithm [21], and the amplitude information of the in-line hologram as the initial value of the iterative process. However, the convergence is afected by the phase-stagnation problem due to insufcient constraints.…”

We put forward a novel hybrid iterative algorithm to improve the imaging quality of digital holography. An off-axis hologram is added to the iteration process via interference and inverse interference process and becomes part of the constraints. A frequency domain filter varying with the number of iterations is used to improve the competitive advantage of low frequency information in the early iterations, while retaining the high frequency information. In practical applications, an additional iterative process is used after averaging filtering to suppress the influence of the imperfect consistency between the reconstructed reference wave and the actual reference wave. Numerical simulations and experiments show that image reconstruction may be significantly improved compared to the conventional method.
