| contents | The phase unwrapping plays a key role in obtaining a ground-truth phase of the wrapped phase. High-accurate unwrapped phases are demanded in various research fields such as optical holography, optical diffraction tomography, and magnetic resonance imaging. Unfortunately, the ground-truth phase is not accessible due to 2pi ambiguity which arises from phase jumps in the wrapped phase. In this paper, we propose a novel approach to improve the accuracy of unwrapping process. We increase the sampling frequency by employing a magnifying objective to reconstruct the unwrapped phase with high accuracy for the application of optical holography. Our result shows that optical magnification enables us to improve the accuracy of the true phase by 42%. We deeply believe that our approach will demonstrate significant achievement in obtaining ground-truth phases in various research fields such as optical holography, magnetic resonance imaging, and optical diffraction tomography. |
