Distributed Fibre Optic Strain Sensing: Long-Term Monitoring for Slopes & Infrastructure in Hong Kong

by Rich Laver (Varadise)


24 November 2022


10:30 am



Distributed fibre optic strain sensing (DFOSS) enables the accurate measurement of strain, temperature and vibration along the entire length of a fibre optic cable. The durability and low cost of the cable make it ideal for the comprehensive long-term monitoring of extensive structures. It is no wonder that the last 20 years has seen DFOSS adopted worldwide for an ever-broadening range of monitoring applications, including structural health, soil movement, traffic congestion and intrusion detection. To date the uptake in Hong Kong has been experimental, but the technology looks set to bring big benefits, particularly for landslide mitigation and infrastructure health monitoring. This webinar will delve into how DFOSS works, its benefits and applications, along with a couple of successful case studies implemented by the presenter.
