报告摘要：

在过去20年中，光纤通信技术一直保持迅猛发展；光学传感技术也从中受益良多。起初光学传感技术是为了解决通信行业的应用需求而出现，并被一度认为与通信行业的关系并不密切。然而，现在的光学传感技术已经站稳了脚跟，并且在新的应用需求中，以崭新的技术不断给人带来惊喜。我将会讨论我在Aston光子学研究所从事的几种特殊的光学传感技术研究，包括光光纤布拉格光栅、长周期光纤光栅和表面等离子体共振技术。我将在三个例子中分别介绍这三种传感技术。首先，利用光纤光栅检测呼吸功能和基于形状传感阵列的局部胸椎运动检测技术。其次，局部表面等离子共振技术在气相互液相化学传感中的应用。最后我将介绍长周期光纤光栅在磁场传感中的应用。

Over the last two decades there has been a rapid expansion of fibre optic telecommunications. One area that has benefited from this growth is photonic sensing, which has utilised the technology developed to meet the demands in telecommunications and was once considered to be telecommunications’spoor relation. However, nowadays photonic sensing is standing on its own feet and forging ahead with new technologies along with promising new and exciting applications. To illustrate the above statement I will talk about specific photonic sensing applications that I have undertaken at the Aston Institute of Photonic Technologies. These will cover various types of sensors and sensing platforms that I have used or created: specifically I will present applications for fibre Bragg gratings, long period periods, surface plasmonresonances and localised surface plasmonresonances. I will cover these types of sensors and sensing mechanisms in three examples: firstly, the use of fibre gratings to monitor respiratory function plethysmography and cardiac-induced localized thoracic motion based upon shape sensing arrays; secondly, the use of localised surface plasmonsfor gas phase chemical sensing and ultra-low concentration chemical sensing in the liquid phase, working with carbon nanotubes or a zinc oxide/platinum matrix and aptamers, respectively; thirdly, using long period gratings with a femtosecond laser sculpted fibre employing magnetostrictionto detect the magnitude and direction of small static magnetic fields.
