ORC Seminars 2011

Recent progress and trends in optical coherence tomography

Speaker: Professor Adrian Podoleanu, Applied Optics Group, School of Physical Sciences, University of Kent

Date: 30 March 2011

Time: 2pm

Venue: B53 Seminar Room


The number of publications in optical coherence tomography (OCT) has doubled in the last 3 years. Traditionally applied to imaging the eye, OCT is now being extended to fields outside ophthalmology and optometry. This explains one of the reasons of rapid OCT developments in the recent years. A second reason is the increase in the acquisition speed by more than 100 times in the last 5 years, mainly due to progress in the technology of fast tunable lasers. Widening its applicability, progress in the core engine of the technology, and impact on development of novel optical sources, make OCT a very active and rapidly evolving field. Principles of time domain and spectral domain OCT technologies will be presented comparatively and how their advantages and disadvantages shaped the range of their specific diagnostic applications. The review will conclude with current research on combination of time domain and spectral domain OCT methods and how Talbot bands can be used to eliminate ghost images in Fourier domain OCT.

Professor Adrian Podoleanuís research interests focus on methods and devices for OCT. He contributed towards development of the en-face OCT imaging as a novel technology to complement the more conventional longitudinal OCT imaging and has generated simultaneously, OCT and confocal images of the retina. He is co-author of 6 chapters in books on OCT, of over 120 peer reviewed journal papers, of more than 200 conference proceedings and of 21 patents (9 awarded). He is one of the topical editors of the Applied Optics. He was awarded a Leverhulme Trust Research Fellowship in 2004, the prize of the Ambassador of Romania to the UK in 2009 and an ERC Advanced fellowship in 2010.
