Paper Abstract

Stability and reproducibility problems in single and multimode fiber optic microbend strain sensors are found to be due to interference between the core mode and cladding modes in the bend region. Microbend strain sensors are stabilized by preventing the interference effect. A high sensitivity fiber optic microbend strain sensor for detecting bending of large mechanical structures has been constructed and tested. OTDR technique has been utilized for detecting strains at several structural points simultaneously by placing many sensors in tandem along a single fiber.
