Improving Separation of Signals from Multiple Physical Quantities Detected by Sensor Arrays
Modern array sensing systems, such as distributed fiber optic sensing, are used in many applications which may record a mixture of responses to multiple physical quantities. In these applications, it may be helpful to be able to separate this mixture of responses into the signals resulting from the …

The study of acoustic properties of P205-doped silica fiber
Silica-based optical fibers have been applied to numerous fields. The interactions between acoustic phonons and the optical wave are involved in several of these applications. A significant stimulated scattering mechanism observed is stimulated Brillouin scattering (SBS), resulting in strong …

Fiber-Optic Sensors for Fully-Distributed Physical, Chemical and Biological Measurement
Distributed sensing is highly desirable in a wide range of civil, industrial and military applications. The current technologies for distributed sensing are mainly based on the detection of optical signals resulted from different elastic or non-elastic light-matter interactions including Rayleigh, …

Time-Frequency Localisation of Distributed Brillouin Optical Time Domain Reflectometry
Distributed fibre optic sensing (DFOS) is essential for structural health monitoring (SHM) of strain changes induced during the lifetime of a structure. Among different DFOS systems, the Brillouin Optical Time Domain Reflectometry (BOTDR) takes the advantages of obtaining full frequency spectrum to …
