Home / Hollow-core fiber optic sensor
Hollow core fiber (HCF) optical sensors are used in applications including Li-ion battery research and development (R&D), robotic arms, civil engineering infrastructural health monitoring, and biosensing. Some of the attributes of HCF optical sensors are small footprints, non-conductance, chemical. Particularly, with the recent advancement of anti-resonant effects, specialty fibers with hollow structures offer a unique sensing platform to achieve highly accurate and ultra-compact fiber optic sensors with large measurement. By replacing the solid core with an air-filled channel, hollow-core fibers (HCFs) allow light to propagate at nearly its vacuum speed, reaching approximately 3×10 8 meters per second.
