Compression and phase reconstruction of temporal fringe pattern data
… methods have been developed to retrieve the phase information from the interferometric fringe pattern. Temporal fringe patterns analysis is fast gaining prominence due to the increased usage of optical metrology techniques for transient phenomena studies. This form of analysis, nevertheless, …

Improved accuracy in susceptibility-based OEF measurements by mitigation of partial-volume effects via combined magnitude and phase reconstruction
… beyond this limit by performing a joint reconstruction using both the magnitude and phase of the complex-valued MRI signal. This method is validated both in numerical simulations and on in vivo data. The ability to perform high-quality fetal brain imaging is hampered by motion of the …

Complex-valued SAR image compression : an approach for amplitude, phase, and gradient recovery
… and limited information content in the phase signal. Traditional compression methods, such as JPEG and JPEG2000, although widely used, often fail to preserve SAR image quality due to their susceptibility to compression artifacts. The continuous capture of high-resolution raw SAR images …

Short pulse generation from semiconductor lasers: characterization, modeling and applications
… devices. Finally, a novel implementation of the Phase Reconstruction using Optical Ultrafast Differentiation (PROUD) technique has been proposed and demonstrated for optical pulse characterization in amplitude and phase. The optical differentiator required in the PROUD technique has been realized …

Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations
In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. Radome diagnostics are acquired in the design process, the delivery control, and in …
