A critical comparison of human face rendering techniques
Human skin exhibits complex light reflectance properties that make it difficult to render realistically. In recent years, many techniques have been introduced to render skin, with varying degrees of complexity and realism. In this thesis, I will implement several of these techniques, and use them …

Holographic Control of Light Propagation in Optical Waveguides
… can now be used to control every aspect of light propagation along an optical waveguide. The application of holographic techniques offers the possibility of faster communication technologies, ultra-thin endoscopes and holographically enhanced sensors. An experimental system is established …

Scalar Scattering Theory and Physics-inspired Optimization for Computational Imaging
… information in photons is further encoded via complex light-matter interactions, this thesis examines several models derived from the scalar wave equation such as the LSE, the Born series, and the beam propagation method. It provides a direct and quantitative analysis of their relationships and …

Quantum simulation and out-of-equilibrium dynamics of quantum gases in optical cavities
… We focus on a two-component Dicke model with complex light-matter couplings, accounting for photon losses. We compute the steady-state phase diagram and find dynamical in- stabilities in the form of limit cycles, heralded by the presence of exceptional points and level attraction. We show that …

Geometry and light in the architecture of Guarino Guarini
… this legacy under the themes of geometry and light. In the 12th century Robert Grosseteste proposed that light was the substantial form of all things, and both he and his followers united spiritual and corporeal light through geometry, thus founding a lightmetaphysic, which flourished in …

Human intent prediction for adaptive lighting based on a limited data scenario
… users with environmental supports such as lighting, air conditioning, motion assistance. Among the different control schemes, lighting is an essential element because it strongly affects people's visual experience and work productivity. The generalized residential lighting system is limited …

Effect of Transition Metal Compounds on the UV Degradation of Polymers
The effects of typical nickel complex light stabilisers as UV screens and as additives were compared in model systems initiated by hydroperoxides or carbonyl compounds. Oxygen absorption studies showed the nickel oxime and nickel dithiocarbamate complexes to impart a stability additional to UV …

Computer-Generated Holography for Areal Additive Manufacture
… computer-generated holography (CGH) to produce complex light patterns in a single pulse. Projecting power to the whole layer at once will mean that the thermal properties of the powders before and after writing can be factored into the processed hologram and part design. It will also …

Multimode Ultrastrong Coupling with FW-BICs in THz Metasurface
… resonators and the resonant coupling leads to light–matter hybridization into two normal modes with an energy separation known as the vacuum Rabi splitting in which the USC regime is reached. For quantum computing platforms, the stronger the coupling the more efficient qubit-photon coupling can …

Nonlinear Light - Matter Interactions of Ultrafast High Intensity Laser Pulses
… offer ultrashort pulses, high intensities, and complex polarizations and wavefronts. These extreme conditions have profound effect on the optical properties and behaviors of electronic and molecular states within a material. The changes in these mechanisms effect generation of nonlinear optics, …

Using Fundamental Properties of Light to Investigate Photonic Effects in Condensed Matter and Biological Tissues
<p>Light possesses characteristics such as polarization, wavelength and coherence. The interaction of light and matter, whether in a semiconductor or in a biological sample, can reveal important information about the internal properties of a system. My thesis focuses on two areas: photocarriers in …
