Helical optical fiber strain sensor |
摘要 |
Strain in concrete is sensed by a helical optical fiber embedded in the concrete and connected at one end to an external light source, and at the other end to a light detector, providing a signal output to an information processor, which provides a display of the strain in the concrete.
