Metallic coatings can improve both sensitivity and mechanical strength of optical fiber sensors (e.g., fiber Bragg grating sensors). Fiber Bragg grating is a periodic modulation in the index of refraction in the core of optical fiber, which can be used for monitoring of physical parameters like strain, temperature and pressure. Deposition of metallic layers on FBGs with specific patterns can improve their sensitivity for measurement of ph...$28.00
