Paper Abstract
Opto-acoustic imaging (OAI) shows particular promise for in-vivo biomedical diagnostics. Its applications include
cardiovascular, gastrointestinal and urogenital systems imaging. Opto-acoustic endoscopy (OAE) allows the imaging of
body parts through cavities permitting entry. The critical parameter is the physical size of the device, allowing
compatibility with current technology, while governing flexibility of the distal end of the endoscope based on the needs
of the sensor. Polymer optical fibre (POF) presents a novel approach for endoscopic applications and has been positively
discussed and compared in existing publications. A great advantage can be obtained for endoscopy due to a small size
and array potential to provide discrete imaging speed improvements. Optical fibre exhibits numerous advantages over
conventional piezo-electric transducers, such as immunity from electromagnetic interference and a higher resolution at
small sizes. Furthermore, micro structured polymer optical fibres offer over 12 times the sensitivity of silica fibre. We
present a polymer fibre Bragg grating ultrasound detector with a core diameter of 125 microns. We discuss the ultrasonic
signals received and draw conclusions on the opportunities and challenges of applying this technology in biomedical
applications.
