SENSOR SYSTEM AND METHOD INCORPORATING FIBRE BRAGG GRATINGS |
摘要 |
<p>A sensor system comprises first and second fibre bragg gratings (FBGs). The two fibre bragg gratings receive light from a common light source and produce respective measurement signals having a spectrum dependent on a measurement signals having a spectrum dependent on a measurand, and a common reference signal. The two measurement signals pass through respective edge filters to respective detectors and a third detector monitors the reference intensity. A processor produces a value for the measurand from the received and detected signals. The system can be used in a temperature compensated strain gauge.</p> |
