This project aims to create a novel class of hybrid optical fibres that open new vistas for magnetic field detection at ambient temperatures in noisy environments. The multidisciplinary project will develop the first fibre laser threshold magnetometry platform that breaks through diamond magnetometry sensitivity limits by cross-cutting established fibre laser technology with the new diamond-glass fibres and magnetometry concepts recently invented by the investigators. Envisaged significant benefits include non-invasive detection of magnetic fields in hard-to-access regions, an area of key interest for remote detection of submarines, early sensing of aircraft corrosion, deep brain imaging of neuronal activities and mineral exploration.

该项目旨在创造一种新型的混合光纤，为噪声环境中环境温度下的磁场检测开辟新的前景。该多学科项目将开发第一个光纤激光阈值磁力测量平台，通过将成熟的光纤激光技术与研究人员最近发明的新的钻石玻璃纤维和磁力测量概念交叉，突破钻石磁力测量灵敏度限制。设想的重大惠益包括对难以进入的区域的磁场进行非侵入性探测，这是远程探测潜艇的一个重要领域，对飞机腐蚀的早期感知，对神经元活动的大脑深层成像和矿产勘探。
