Mean gradient descent: an optimization approach for single-shot interferogram analysis. [PDF]
Complex object wave recovery from a single-shot interference pattern is an important practical problem in interferometry and digital holography. The most popular single-shot interferogram analysis method involves Fourier filtering of the cross term, but ...

Source brightness fluctuation correction of solar absorption fourier transform mid infrared spectra [PDF]
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.

Reducing the impact of source brightness fluctuations on spectra obtained by Fourier-transform spectrometry [PDF]
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-

Data reduction methods for single-mode optical interferometry - Application to the VLTI two-telescopes beam combiner VINCI [PDF]
The interferometric data processing methods that we describe in this paper use a number of innovative techniques. In particular, the implementation of the wavelet transform allows us to obtain a good immunity of the fringe processing to false detections ...

New SAR Interferogram denoising method via sparse recovery based on L0 norm [PDF]
The goal of this paper is to estimate a denoised phase image from the observed noisy SAR interferogram. We proposed a linear model to obtain a sparse representation of the interferomteric phase image.
