Interferometric Methods
… discussion is given of how standard steps in interferometric imaging differ in this new scheme, including calibration. Additionally the first wide field direct imaging correlator is presented, which allows the problems of non-coplanarity to be dealt with for both sparse and dense arrays in a …

Interferometric Synthetic Aperture Microscopy
State-of-the-art interferometric microscopies have problems representing objects that lie outside of the focus because the defocus and diffraction effects are not accounted for in the processing. These problems occur because of the lack of comprehensive models to include the scattering effects in …

Multifocal interferometric synthetic aperture microscopy
We extend interferometric synthetic aperture microscopy (ISAM) to optical coherence tomography (OCT) data collected with multiple positions of the focal plane. Multifocal ISAM achieves spatially invariant resolution like ISAM by applying the solution of the inverse problem to the forward model for …

Space-time imaging and interferometric microscopy
Advances in mode-locked sources allow ultrafast optical fields to be programmed both spatially and temporally. Sophisticated electronics and computer control increase the complexity of measurements that one can make on optical fields. Computer modeling and simulation have also advanced to where one …

Surface reconstruction from interferometric ISAR data
… multistatic radar, it is possible to generate 3D Interferometric ISAR (IFSAR) point cloud images. In this thesis, two original techniques for automatically generating models of rigid bodies from IFSAR point clouds are explored. One technique extends the concept of the visual hull to a composite …

Analysis of interferometric SAR for topographic mapping
… separate passes (repeat-pass interferometry). An interferometric image (interferogram) is formed by multiplying pixels from the reference image with the complex conjugate magnitudes of pixels from the second registered image. This thesis reviews the basic principles of SAR imaging. These are …

Interferometric experiments towards advanced gravitational wave detectors
… been built since the 1960s, in the form of both interferometric detectors and resonant mass devices. Interferometric detectors currently represent the most promising form of detector, due to their relatively wide-band response to gravitational wave signals and promising levels of sensitivity. In …

Motion Compensation of Interferometric Synthetic Aperture Radar
Deviations from a nominal, straight-line flight path of a synthetic aperture radar (SAR) lead to inaccurate and defocused radar images. This thesis is an investigation into the improvement of the motion compensation algorithm created for the BYU inteferometric synthetic aperture radar, YINSAR. The …
