چکیده

A new signal-processing technique is proposed that involves a phase-resolved correlation method that one can use to determine the phase distribution of low-coherence interferograms. This method improves the sensitivity and resolution of low-coherence interferometers. The depth structure of an aluminum oxide-coated aluminum mirror was determined by use of a low-coherence interferometer with this method. Three signal peaks were successfully extracted from a noisy interferogram.

طراحی، ساخت و مشخصه یابی پله های فازی شیشه ای برای کاربرد در تداخل سنجی جابجایی فاز

In this paper, we report on the design and fabrication of a low-cost phase shifter for application in phase shifting interferometry. Phase shifting interferometry is a powerful method for surface characterization. It uses interference data recorded during a series of predetermined phase shifts to recover the induced phase by the object surface. These controlled phase shifts are typically perfor...

Algorithm of Interferometric Coherence Estimation for Synthetic Aperture Radar Image Pair

Interferometric coherence is an important indicator of reliability for interferograms obtained by interferometric synthetic aperture radar (Interferometric SAR, InSAR). Areas with low coherence values are unsuitable for interferometric data processing. Also, it may be used as a classification parameter for various coverage types. Coherence magnitude can be calculated as an absolute value of the...

Isolation of Atmospheric Artifacts in Differential Interferometry for Ground Displacement Detection : Comparison of Different Methods

Radar differential interferometry theoretically allows precise detection of ground motion using radar phase information when a series of radar acquisitions are available. However, coherence loss and atmospheric heterogeneities are limiting factors that can corrupt radar interferograms. Concerning atmospheric artifacts, a classical and simple solution is averaging them out by addition of several...

Dual-channel low-coherence interferometry and its application to quantitative phase imaging of fingerprints.

We introduce an off-axis, wide-field, low-coherence and dual-channel interferometric imaging system, which is based on a simple-to-align, common-path interferometer. The system requires no optical-path-difference matching between the interferometric arms in order to obtain interference with low-coherence light source, and is capable of achieving two channels of off-axis interference with high s...

Spatial Coherency of the Synchrotron Radiation at the Visible Light Region and Its Application for the Electron Beam Profile Measurement

A spatial coherenceies of SR beam at visible light region were measured both σ and π-polarized components at Photon Factory. A wave-front division type polarized interferometer was designed and constructed for this experiment. Interferograms were observed clearly in the vertical direction. π phase difference of the interference fringe was observed between interferograms corresponding to σ and π...
