Distributed Strain and Temperature Sensing (DSTS)
Foresight™, from OZ Optics, is a sophisticated Distributed Strain and Temperature Sensor (DSTS) system based on Brillouin scattering in an optical fibre. It can measure subtle changes in both temperature and strain along the length of the fibre over time, or the rapid location detection of a major disturbance within a second.
By wrapping or embedding a fibre inside a structure, such as an oil pipeline or dam, detection of the structure being strained or heated/cooled is possible, allowing for pre-emptive maintenance. Such monitoring capability is invaluable in critical structures where cracks and failure could involve loss of life or other unprecedented costs.
Foresight™ can also detect and report larger signals within one second with only a slight loss of accuracy. This sort of response speed is ideal for security applications or strains caused by earthquakes where an immediate measurement and reaction may be required.
