Brief summary of PI research / research group / centre activity (2 or 3 lines max):
The OFSRC is engaged in the investigation of optical and optical fibre sensors for a wide range of
application areas. Sensors have been designed for biomedical e.g. bladder pressure and total
haemoglobin concentration as well as environmental e.g. atmospheric pollutant gases and
radiation level.
Title & brief description of PhD project (suitable for publication on web):
An Optical Fibre Sensor for Measurement of Harmful Algal Blooms (HABs) in Freshwater and
Marine Applications
It is proposed to design, construct and test an optical fibre sensor for the measurement of
contamination of freshwater lakes and marine environments based on a novel design of a coated
optical fibre sensor. The sensor to be investigated will be based on the evanescent field
detection, a method extensively investigated within OFSRC coupled to enhanced sensitisation by
use of Long Period Gratings (LPGs). The sensors will be fabricated in all silica optical fibres as well
as Plastic Optical Fibres (POFs) and both types of sensor will fully tested in their environment.
Extensive Sensor Fabrication facilities are available at the Labs of OFSRC and through its
participation in COST Action TD1001 to state of the art optical fibres and internationally unique
research facilities e.g. specialist optical fibre draw towers and specialist fibres e.g. Photonic
Crystal Fibres. Access to Marine and freshwater systems will be available through linkage with
the National SMART BAY initiative of which OFSRC is an active member.
