Polarimetric Interferometry and Differential Interferometry

This Lecture mainly based on [1, 2] presents the role of Polarimetry in SAR Interferometry. A general formulation for vector wave interferometry is presented that includes conventional scalar interferometry presented in the respective former lecture as a special case. Based on this formulation, the coherence optimization problem can be solved to obtain the optimum scattering mechanisms that lea...

Differential spectral interferometry: an imaging technique for biomedical applications.

Differential spectral interferometry (DSI), a novel method of biomedical imaging that combines the high dynamic range of optical coherence tomography (OCT) with inherently parallel low-bandwidth image acquisition of spectral interferometry (SI), is described. DSI efficiently removes the deleterious dc background inherent in SI measurements while maintaining the parallel nature of SI. We demonst...

Longitudinal-differential interferometry: direct imaging of axial superluminal phase propagation.

We introduce and demonstrate a new interferometric method called longitudinal-differential (LD) interferometry, which measures the spatially resolved phase difference of the scattered field by an object relative to the illumination. This method is combined with a high-resolution interference microscope that allows recording three-dimensional field distributions in amplitude and phase. The metho...

Normal and Differential SAR Interferometry

Wolfgang Keydel Microwaves and Radar Institute German Aerospace Research Centre (DLR), Oberpfaffenhofen Contact Address: Mittelfeld 4 D-82229 Hechendorf Germany E-mail: [email protected] Abstract SAR Interferometry explores the height structure inside a Radar pixel. Two antennas separated with a so called baseline distance B in cross velocity direction take two independent images from the...
