Optimization of a High-Energy X-Ray Inline Phase Sensitive Imaging System for Diagnosis of Breast Cancer
… the radiation dose. The conventional x-ray imaging technique relies on the attenuation characteristics of a tissue to produce imaging contrast. However, the similar attenuation characteristics of normal and malignant breast tissue present a challenge in differentiating between them using …

Materials in extreme conditions : experimental developments and studies of systems far from equilibrium
… also refined; an existing single-shot multiframe imaging technique was extended into phase sensitive imaging. These techniques are applied to a range of material systems (energetic materials, brittle solids and biological membranes), pushing them far from equilibrium, and studying their response. …

Micro-motion detection by optical coherence tomography (OCT) and its clinical applications
… aim of this thesis is to develop a non-contact phase-sensitive imaging technique which is suitable for functional imaging in the micron range which also has the potential for quantitative analysis of relative properties resulting from an appropriate image processing.<br/><br/>Concerning imaging …

THz polaritonics : optical THz generation, detection, and control on a chip
… they can be amplified and guided. Time-resolved phase-sensitive imaging lets us capture movies of THz waves as they propagate at the light-like speeds. I developed polaritonics methodologies and used the platform to study various microstructures interacting with THz waves. I began technique …

Developments and applications of THz polaritonics, efficient THz generation, and single-shot THz detection
… that the teraherz fields can be recorded using phase-sensitive imaging technique to observe the full spatiotemporal evolution of the field. In the free space regime, the terahertz field propagates in free space between a transmitter and a receiver. By using appropriate crystals and focusing …

Developments in time-resolved ultrafast imaging and spectroscopy at terahertz frequencies
… by the lack of both high power THz sources and sensitive THz detectors. Over the past few years, it has become more 'routine' to generate and detect THz radiation between 0.1-10 THz, but there remains much room for improvement. In this work, I describe recent developments in THz detection …
