Abstract
Stimulated Brillouin Scattering (SBS) is utilized in the optical fiber sensor distributed measurement system. BOTDA (Brillouin Optical Time Domain Analyzer), one of these devices, shows a capability to obtain strain and temperature simultaneously with high precision over a distance of tens' kilometers. This makes BOTDA an expectable candidate device to realistic FOBSS (Fiber Optic Based Smart Structure). The present paper suggests a computer based tomography method to enhance the spatial resolution of BOTDA which can be solved to an artificially specified segment of centimeter order or less; this is one or two orders smaller than the present art of view. The presented result is considered as an important progress towards widely commercial applications.
