Even-order dispersion cancellation, an effect previously identified with frequencyentangled photons, is demonstrated experimentally for the first time with a linear, classical interferometer. A combination of a broad bandwidth laser and a high resolution spectrometer was used to measure the intensity correlations between anti-correlated optical frequencies. Only 14% broadening of the correlatio...

Phase noise reduction is one of the key steps for InSAR data processing. In this paper, a novel phase filtering method proposed. The main innovation and contribution research to, (1) incorporate local fringe frequency (LFF) compensation technique into non-local to include more independent identically distributed (i.i.d.) samples filtering; (2) modify filter from three aspects: 1) executing in c...

1: — When burst-mode data is used for interferometry, the burst cycles must be well-aligned, as well as the normal condition of having the Doppler centroids well-aligned. In this paper, we show the phase error effects of different burst lengths, various burst misalignments, and of receiver noise.

In this work, we report about optical spectrometry using gold nano-structures printed on a polymer based integrated optical waveguide. The optical waveguide is a single mode buried waveguide, having dimensions of 3x2.2μm. It is made from a combination of photo-polymerizable materials and is fabricated by photolithography on a glass substrate. To sense the electric field inside the waveguide, a ...

Along-track interferometric synthetic aperture radar (AT-InSAR) systems are used to estimate the radial velocity of targets moving on the ground, starting from the interferometric phases, obtained by the combinations of two complex SAR images acquired by two antennas spatially separated along the platform moving direction. Since the radial velocity estimation obtained from a single-phase interf...

Historically, the Kyrgyz Republic and neighboring countries have experienced numerous strong earthquakes. Our research focused on investigation of surface deformations caused by 5 earthquake events which had occurred during 2014-2017. A Differential Interferometric Synthetic Aperture Radar (DInSAR) technique was applied for Sentinel-1 data acquired before after events. The pairs images were pro...

This paper is focused on spaceborne Differential Interferometric SAR (DInSAR) for land deformation measurement and monitoring. In the last two decades several DInSAR data analysis procedures have been proposed. The objective of this paper is to describe the DInSAR data processing and analysis tools developed at the Institute of Geomatics in almost ten years of research activities. Four main DIn...
