| Popis: | Fiber Bragg grating (FBG) sensors are optical strain gauges embedded in an optical fiber. Using elementary beam theory and geometry, it is shown that 3-D shape sensing can be performed using parallel arrays of sensors on the surface of a cylindrical rod. The mathematics is explained in detail. Because FBG sensors are immune to electromagnetic interference, they can be used to perform shape sensing on cylindrical objects utilized in high-voltage transmission systems, such as the core support rods of high-temperature low-sag conductors. |
