Development and performance testing of OTDR-based twisted fiber optic strain sensors
To accurately monitor the deformation patterns of rock masses in high-stress soft rock tunnels, a coiled optical fiber strain sensor was developed using optical time-domain reflectometry. The effects of spring diameter, pitch, number of turns, and compression displacement on fiber optic loss and sen...
