OPTICAL FIBRE PRESSURE SENSOR COMPRISING IN-CORE CAVITY AND GRATING |
摘要 |
An optical fiber capable of measuring pressure or pressure difference with high sensitivity is disclosed. The optical fiber (1) comprises a core (2) having a Bragg grating (4) and an internal closed cavity (5), wherein the Bragg grating is associated with the internal closed cavity. By means of the optical fiber, there is no need for external components for mechanically imparting the optical fiber to enable measurement of pressure by means of the optical fiber. |
