NEW ORLEANS– OZ Optics is showcasing its ForeSight family of fiber optic Brillouin distributed strain and temperature sensors at the Subsea Tieback Forum & Exhibition.
Distributed sensing provides a direct method of measuring the changes in strain and temperature along the entire length of an optical fiber. The company has unveiled a new Brillouin optical time domain reflectometer (BOTDR) module based on spontaneous Brillouin scattering. This module complements its existing Brillouin optical time domain analysis (BOTDA) line of products. The company says that if there is a break somewhere on the fiber, this unit can still measure strain/temperature up to the point of the break. The BOTDR system is available either as a stand-alone unit, or combined in a dual BOTDA/BOTDR measurement system.
The sensor uses standard optical telecommunications fiber, thereby leveraging the enormous economies of scale from fiber optic communication networks. The new system is ideal for temperature and strain monitoring of oil and gas pipelines. Brillouin sensors detect corrosion, buckling, and micro cracks in large structures.
