Silica Optical Fiber (SOF) SensorsFor an important number of environmental monitoring and industrial applications fiber-optic sensor technology offers several advantages for significant metrological improvement through:
The scientific community is interested in:
High sensitivity
Immunity to electromagnetic interference
Safety in the corrosive environments
Fast response
This technology is suitable for distributed measurements and it is, by definition, compatible with the fiber-optic communication networkscompatible with the fiber-optic communication networks
New devices able to provide high performance sensing mechanism and multiplexing capability.
When the optical probe is exposed to a target analyte, its molecules are When the optical probe is exposed to a target analyte, its molecules are adsorbed within the sensitive layer, changing its thickness and adsorbed within the sensitive layer, changing its thickness and
complex dielectric function and thus the optical signal reflected at the complex dielectric function and thus the optical signal reflected at the fiber film interface.fiber film interface.
HiPco SWCNTs (purchased by CNI) films have been deposited
