Cytoflow Optics Analysis
… of this project was to create a design for the optics assembly of the cytometer. Prototypes were constructed and then tested to analyze results. Data was collected then analyzed using a specific standard across all cytometers. Using these guidelines a result was yielded that helped to improve …

Cyclostationary statistical optics
Pulsed, optical fields are treated theoretically within the framework of cyclostationary random processes. Propagation-induced effects for stochastic, pulsed fields that are either beam-like or plane waves are examined in the context of interferometric and spectroscopic measurements. Propagation of …

The Adaptive Optics Lucky Imager: combining adaptive optics and lucky imaging
… obtained by combining the techniques of adaptive optics and lucky imaging. The Adaptive Optics Lucky Imager (AOLI), being developed at Cambridge as part of a European collaboration, combines these two techniques in a dedicated instrument for the first time. The instrument is designed initially for …

Photorefractives for fast optics
This thesis describes an experimental and theoretical study into the nonlinear optical<br/>properties of novel photorefractive materials and devices. The focus of the work is<br/>centred on bringing together the attractive attributes of inorganic and organic<br/>materials in a single hybrid device …

Marine optics: field radiometry
In situ optical radiometric methods for the determination of seawater apparent optical properties are comprehensively addressed with the final objective of quantifying measurement uncertainties for remote sensing applications. Emphasis is placed on the presentation and assessment of calibration and …

Adaptive Optics for Stellar Interferometry
… seeing will need the consideration of adaptive optics (AO). Accordingly, this dissertation will first examine the problem that seeing causes in stellar interferometers. The application of Adaptive Optics in Stellar Interferometry will then consider these results to achieve the final goal: …

Integrated optics for holographic video
The goal of this research is to fabricate a guided-wave, two-axis scanner and to modify the design of the MIT holovideo system to take full advantage of the scanner's high bandwidth and two-dimensional deflection. The new display geometry will be designed to use the guided-wave scanner coupled with …

Metalenses and Refraction Problems in Optics
This thesis studies several refraction problems involving metalenses using optimal transport techniques. Metalenses are ultra-thin surfaces that are composed of nanostructures to focus light. Mathematically they can be represented by a pair (Γ, Φ) where Γ is a surface in R^3, and Φ is a C^1 …

Parity-time and supersymmetry in optics
… in this dissertation we show that optics can provide a fertile ground for studying, observing, and utilizing some of the peculiar symmetries that are currently out of reach in other areas of physics. In particular, in this work, we investigate two important classes of symmetries, …

Third-order charged particle beam optics
… An alternate way of describing charged particle optics is also presented. It is based on a Hamiltonian treatment and uses certain symplectic operators, which are defined in terms of Poisson brackets, to parametrize the transfer map of a system. We apply this approach to the fringing field problem …

Third-order charged particle beam optics
The motion of a charged particle through a magnetic field configuration can be described in terms of deviation from a certain ideal trajectory. One uses power series expansion of the phase-space coordinates to obtain the transfer matrices for a particular optical system.
