New Interferometric Phase Unwrapping Method Based on Energy Minimization From Contextual Modeling
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Two-dimensional phase unwrapping is a critical processing procedure of synthetic aperture radar interferometry. This operation becomes even more difficult in the presence of noise.

Photolithographic fabrication method of computer-generated holographic interferograms [PDF]
, 1989 We consider the fabrication of high-quality interferogram-type diffractive optical elements with conventional photolithographic techniques and compare the results with those achievable with electron-beam lithography. The fringes associated with the phase

Analyzing laser-plasma interferograms with a Continuous Wavelet Transform Ridge Extraction technique: the method [PDF]
, 2001 Laser-plasma interferograms are currently analyzed by extracting the phase-shift map with FFT techniques (K.A.Nugent, Applied Optics {\bf 18}, 3101 (1985)).

Reducing the impact of source brightness fluctuations on spectra obtained by Fourier-transform spectrometry [PDF]
, 2007 We present a method to reduce the impact of source brightness fluctuations (SBFs) on spectra recorded by Fourier-transform spectrometry (FTS). Interferograms are recorded without AC coupling of the detector signal (DC mode). The SBF are determined by low-

Source brightness fluctuation correction of solar absorption fourier transform mid infrared spectra [PDF]
Atmospheric Measurement Techniques, 2011 The precision and accuracy of trace gas observations using solar absorption Fourier Transform infrared spectrometry depend on the stability of the light source. Fluctuations in the source brightness, however, cannot always be avoided.
