Interferometric Synthetic Aperture Radar has the capability to provide the user with the 3-D-Information of land surfaces. To gather data with high height estimation accuracy it is necessary to use a wide interferometric baseline or a high radar frequency. However the problem of resolving the phase ambiguity at smaller wavelengths is more critical than at longer wavelengths, as the unambiguous ...

Surface topography measuring interference microscopy is a three-dimensional (3D) imaging technique that provides quantitative analysis of industrial and biomedical specimens. Many different instrument modalities configurations exist, but they all share the same theoretical foundation. In this paper, we discuss unified framework for 3D image (interferogram) formation in microscopy. We show how s...

Combination of several interferograms of a same area, each having its own ambiguity of altitude, allows producing a combined interferogram with either a better signal to noise ratio or a lower ambiguity of altitude, unreachable from a single interferometric pair. InSAR baseline combination by summation of interferograms allows reaching peculiar equivalent baselines while increasing signal to no...

We present a method for interferometric imaging with the Large Binocular Telescope (LBT) at optical and infrared wavelengths. For example, at λ = 550 nm a resolution of 6.1 mas can be obtained. The uv-coverage is excellent due to the small distance between the two 8.4 m mirrors. We show laboratory and computer experiments of LBT speckle masking interferometry. The raw data were produced by simu...

We introduce a novel method for retrieving the phase from a spectral shearing interferogram, based on wavelet-transform technique. We demonstrate with both theoretical and experimental data that this technique provides an alternative and reliable technique for phase retrieval, particularly for highly structured pulse spectra.

We describe a novel effect involving odd-order dispersion cancellation. We demonstrate that odd- and even-order dispersion cancellation may be obtained in different regions of a single quantum interferogram using frequency-anticorrelated entangled photons and a new type of quantum interferometer. This offers new opportunities for quantum communication and metrology in dispersive media.

A study of the interferometric characteristics of manmade features is presented. Tests for the assessment of their phase stability are applied for two case studies. The results indicate that small features show spatially homogeneous phase information in a single interferogram and that this information remains stable also in time even at the level of single pixels.

Registration of SAR images is required for interferometric processing and multitemporal analysis. A procedure which allows simultaneous generation and registration of SAR images from spaceborne sensors is presented. The procedure is based on the properties of the chirp scaling algorithm and is used in a interferometric processor to generate the interferogram, the fringes and the coherence map.
