چکیده
Phase unwrapping is the reconstruction of the originaltrue phase of a wave from its modulo 2p values. It origi-nates in a variety of applications, such as synthetic aper-ture radar, magnetic resonance imaging, and adaptiveoptics. In this article, the problem of two-dimensionalphase unwrapping is defined and the challenges are ad-dressed. A variety of established approaches to the prob-lems are reviewed and compared, and their advantagesand disadvantages are discussed. Among the many phaseunwrapping applications, the article focussed on magneticresonance imaging and explains how phase unwrapping isused in field mapping, inversion recovery, and flow imag-ing.Shankar gkramu / Art No. ebs1356 1^12

InSAR Phase Unwrapping by Transforming Sparce Data into a Regular Space
Phase unwrapping is one of the most important parts of InSAR techniques. In order to estimate the grand surface displacements, interferomtric phases modulated between 0 to 2π must be unwrapped. Based on the use of either the conventional method or persistent scatterer (PS), phases will be spread both regularly and irregularly. The phases of PSs can be unwrapped by reducing phases into a regular...

متن کاملTile-Based Two-Dimensional Phase Unwrapping for Digital Holography Using a Modular Framework.
A variety of physical and biomedical imaging techniques, such as digital holography, interferometric synthetic aperture radar (InSAR), or magnetic resonance imaging (MRI) enable measurement of the phase of a physical quantity additionally to its amplitude. However, the phase can commonly only be measured modulo 2π, as a so called wrapped phase map. Phase unwrapping is the process of obtaining t...

متن کاملA Tool for 2+1d Phase Unwrapping: Application Examples
This paper is focused on a new 3D phase unwrapping procedure, named 2+1D unwrapping, which works on large stacks of differential interferometric SAR data. The procedure firstly performs a 2D phase unwrapping, which is followed by a kind of 1D phase unwrapping, i.e. the phases are unwrapped by connecting them along the time. For this reason the entire procedure performs a 2+1D phase unwrapping. ...
