Several novel types of optical fibre sensors will be reported. These includes fibre-tip micro-cavity sensors for pressure and temperature measurement, high temperature photonic crystal fibre and sapphire fibre grating sensors, highly sensitive strain and bent sensors based on structural long period fibre gratings, and sensitive acoustic pressure sensors with hollow core photonic bandgap fibres.BIOGRAPHY: Wei Jin received a BEng degree from Beijing University of Aeronautics and Astronautics, China, in 1984, and a Ph.D degree from University of Strathclyde, Scotland, in 1991. Afterwards was employed as a Postdoctoral Research Fellow at University of Strathclyde till the end of 1995. He joined the Department of Electrical Engineering of the Hong Kong Polytechnic University as an assistant Professor in 1996 and was promoted to an associate professor in 1998 and a professor in 2003.
His research interests are photonic crystal fibers and devices, optical fiber sensors, fiber lasers and amplifiers, optical gas detectors, condition monitoring of electrical power transformers, and civil and mechanical structures. He edited 2 books, published over 400 technical papers and holds 10 patents in the area of fiber optic devices and sensors.
