With Fiber Segment Interferometry (FSI), Kistler offers an innovative fiber-optic measurement technology for highly precise detection of temperature, strain, as well as 2D and 3D shape. The solution enables distributed measurements along a single optical fiber with high resolution and dynamic performance – even under extreme conditions. Thanks to its immunity to electromagnetic interference, compact design, and minimally invasive integration, FSI is ideally suited for applications in high-voltage environments, battery development, structural analysis, as well as mechanical engineering and aerospace. Combined with sensors and interrogators, the system delivers reliable real-time data for advanced testing, monitoring, and validation tasks.
