Computational time-resolved imaging
… not exploited. This thesis explores the use of time-varying optical illumination and time-resolved sensing along with signal modeling and computational reconstruction. Its purpose is to create new imaging modalities, and to demonstrate high-quality imaging in cases in which traditional …

Rapid time-resolved brain imaging with multiple clinical contrasts using wave-shuffling
Magnetic Resonance Imaging (MRI) is a non-invasive but slow biomedical imaging modality that produces images of multiple desirable contrasts. Currently, multiple receive channels are used in MRI to exploit redundancy and sample fewer data points for faster acquisition. Wave-CAIPI is a recently …

The Study of 3D Micro-fluid Printing in Aqueous Two-phase System
… for dispensing the ink phase solution. Time-resolved imaging on the 2D pattern under UV light was used to study the stability of the structure in the matrix. The 3D printing performance of this printing system was tested based on the consistency of the printing results.</p>

Statistics In Diffractive Imaging
… reconstruction techniques in diffractive imaging when the data is exceptionally noisy and when crucial experimental parameters are unmeasured. In particular, this work focuses on two applications of diffractive imaging, single particle imaging with unoriented data and ultrafast magnetic …

Single atom imaging with time-resolved electron microscopy
… (STEM) have opened up new possibilities for time-resolved imaging at the atomic scale. However, rapid imaging of single atom dynamics brings with it a new set of challenges, particularly regarding noise and the interaction between the electron beam and the specimen. This thesis develops a set …

Time Resolved Light Sheet Microscopy
… to new methods of prevention and treatment. Time-correlated single photon counting fluorescence lifetime imaging microscopy is just one of the tools used to carry out this line of research. Here we demonstrate a direct interaction between two proteins involved in gene regulation and …

Cyclometallated platinum and iridium complexes with thiolate ligands, and novel bioimaging agents inspired by dynamic disulfide interchange reactions
… for use in chemosensing applications and as bioimaging agents. This final topic is an area of increasing study as a result of the diverse and tuneable excited states of such molecules, and their advantages over conventional organic emitters such as reduced photobleaching and long luminescence …

Low-dose imaging of liver diseases through neutron stimulated emission computed tomography: Simulations in GEANT4
… (NSECT) is a non-invasive, tomographic imaging technique with the ability to locate and quantify elemental concentration in a tissue sample. Previous studies have shown that NSECT has the ability to differentiate between benign and malignant tissue and diagnose liver iron overload while …

Nanometer scale observation of magnetization textures induced by ultrashort laser pulses
… demagnetize magnetic materials on a femtosecond timescale, but even reverse the magnetization in certain (anti-)ferromagnetically coupled alloys and multilayer systems. Very recently, it was demonstrated that laser pulses create topological magnetic solitons called magnetic skyrmions in …

Developments and applications of THz polaritonics, efficient THz generation, and single-shot THz detection
… 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 optics, it is …

Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications
… capable of resolving the dynamics in time have become more frequent. In the thesis, a method for simultaneously extending the measurements to the third spatial dimension and to the time dimension, is presented. A high repetition rate laser and detection system is combined with …
