Description
The OZ Optics Foresight™ series of fiber optic Distributed Strain and Temperature Sensors (DSTS) BOTDA modules are sophisticated sensor systems that utilize stimulated Brillouin scattering in optical fibers to accurately measure changes in strain and temperature along the length of an optical fiber.
These modules provide real-time, high-resolution measurements, enabling users to detect and address potential issues before failure occurs. The DSTS system offers simultaneous and independent measurement of temperature and strain, allowing for the identification of temperature-induced strain regions.
