Depth of field reduction for miniature-camera imaging
(NUI Galway, 2020-08-25)This thesis investigates the reduction of depth-of- field for miniature camera systems, such as the ones embedded in smartphones. The work on digital shallow depth-of- field is already mature and implemented in most modern ... -
Detection of faint exoplanets in multispectral data
(NUI Galway, 2019-04-15)The detection of extrasolar planets is extremely difficult due to their extreme faintness and proximity to their parent stars. Direct, ground-based detection is particularly challenging and despite the incredible contrast ... -
Eye modelling for personalised intraocular lens design
(2012-08-03)Approximately 20 million cataract operations are performed per year worldwide, routinely removing the opaque cataractous lens and implanting an artificial intraocular lens (IOL). Modern technologies used to treat cataract ... -
A fibre based quad-cell wavefront sensor for high speed adaptive optics
(2014-05-20)The genesis of this thesis came out of the difficulties encountered when trying to apply adaptive optics correction to optical fields that contain scintillation (specklelike amplitude fluctuations). These scintillated ... -
The Optical Signatures of Magnetospheric Phenomena at the End of the Main Sequence and Beyond
(2012-10-22)In recent years, very low mass stars and brown dwarfs, together known as ultracool dwarfs, have unexpectedly been detected as a radio transient source, where periodic bursts of radio emission were also discovered. Periodicity ... -
Shaping the focal field in three dimensions using polarisation and phase
(2013-05-27)Vectorial polarimetry is a novel high-resolution microscopy technique with potential applications in the characterisation of nano-materials, sub-diffraction limit microscopy, and single molecule imaging. Previous work had ...
