Novel optical sources for OCT (HIRESOMI)

Development and Fibre Integration Issues for OCT, using Fibre Optics

Researcher: Irina Trifanov

Supervisors: Professor Adrian Gh. Podoleanu, University of Kent, and Dr. Antonio. B Lobo Ribeiro, Mutiwave Photonics (now with the Faculty of Health Sciences, University Fernando Pessoa, Porto, Portugal

Project funding: HIRESOMI 

Outline

The project was a joint collaboration between University of Kent, Canterbury, UK (host institution) and Multiwave Photonics, Maia, Portugal (guest institution). The project began with a 12 months training and research period in Optical Coherence Tomography (OCT) at University of Kent. The second part (24 months) was carried out at Multiwave Photonics. The company offers innovative optical sources based on fiber-optic technologies, as well as product design, product development and engineering services aimed at developing and selling cost-effective and reliable products and solutions.

The major part of the PhD project was focused on development of new fibre-based optical sources for Optical Coherence Tomography. Two compact sources based on 1 micron technology were developed and tested: a broadband source (BBS) and a swept source (SS). Their specifications have been carefully tailored to meet the demands required explicitly for medical applications (ophthalmology). The effort has been mostly market driven, as there is a high demand in developing sources particularly for this wavelength region due to significant improvements in image penetration.
