TL;DR: It is demonstrated that interference phase can be obtained from a fringe pattern using the spatial domain method known as spatial synchronous detection (direct interferometry) but without the usual fringe carrier introduced into the interferometer.

TL;DR: Using off-axis electron holography under Lorentz microscopy conditions to experimentally determine the magnetization distribution in individual cobalt (Co) nanowires, and scanning precession-electron diffraction to obtain their crystalline orientation phase map, demonstrates the applicability of the method employed and provides further understanding on the effect of crystalline structure on magnetic properties at the nanometric scale.

TL;DR: Nonlocal means (NLM) and its related adaptive kernel-based filtering methods for speckle noise reduction in DSPI fringes are demonstrated and it is observed that the proposed filtering methods preserve the edge information of the DSPi fringes, which is evaluated on the basis of the edge preservation index of the resultant filtered images.

TL;DR: Three-dimensional digital holography with three object-illuminating beams has been successfully used for the detection of surface strain in metallic objects and the results show the conversion of the complete surface displacement field into a surface strain field.

TL;DR: The obtained results corroborate the effectiveness of the proposed method for speckle noise reduction in Speckle fringes in terms of PSNR and Q and observe that the method provides better qualitative and quantitative results.
