Fibre optic sensing device and method |
| 摘要 |
A detector comprises an optical radiation source (10) and a length of optic fibre (18) sensitive to local variations in a physical variable. Changes in radiation back-scattered by the fibre are received by a detector (24) which gives an output dependent on local changes in the physical variable.
