Sumario: | Optical fiber-based sensors are non-invasive and suitable instrumentations for physical sensing. In this technology, signals are transmitted through pulses of light and are not affected by electromagnetic interference or electrical noise. Although optical fibers perform well at typical operating temperatures, their properties at cryogenic temperatures down to 1.6 K under ultrahigh vacuum remain largely unknown. Future applications in quantum computing, superconducting research, and aerospace will all require cryogenic technologies. For such cold applications, a solid understanding of optical fiber performance and losses is crucial. This study evaluates the optical fiber losses for discrete and distributed strain sensing down to cryogenic temperatures (1.6 K). |
