Phase extraction from optical interferograms in presence of intensity nonlinearity and arbitrary phase shifts
We present an advanced technique to retrieve phase from multiple optical interferograms containing intensity nonlinearity and random phase shifts, which are common in practice. The proposed algorithm employs a least-squares iteration scheme to detect harmonics up to the pth order and arbitrary phase shifts simultaneously, and the phase distribution can be accurately extracted from (2pþ 1) inter...
متن کاملPhase determination from mostly one-sided interferograms.
We show how to detect and correct for nonlinear phase shifts in a mainly one-sided interferogram of an emission-line source. We simultaneously detect and correct for an out-of-phase emission background from the spectrometer. The method requires two auxiliary spectra, one of a strong continuum source, and one of an emission-line source with little or no continuum.
متن کاملInSAR phase analysis: Phase unwrapping for noisy SAR interferograms
Interferometric Synthetic Aperture Radar (InSAR) exploits the phase difference between two complex radar signals for extracting information about the earth surface. Some significant application fields concerned by InSAR techniques are Digital ElevationModel (DEM) generation (Graham, 1974), geophysical hazard analysis (Massonet & Feigl, 1998), desertification (Bodart et al., 2009), deforestation...
متن کاملConsistent Phase Estimation for Recovering Depth From Moiré Interferograms
Moiré interferometry is a common tool if depth estimation from a single image frame is desired. It uses the interference of periodic patterns to measure the topology of a given surface. The actual depth estimation relies on the consistent phase estimation from the interferogram. We show that this task can be simplified by estimating the image phase and the local image orientation simultaneously...
متن کاملPhase statistics of interferograms with applications to synthetic aperture radar.
Interferometric methods are well established in optics and radio astronomy. In recent years, interferometric concepts have been applied successfully to synthetic aperture radar (SAR) and have opened up new possibilities in the area of earth remote sensing. However interferometric SAR applications require thorough phase control through the imaging process. The phase accuracy of SAR images is aff...
