Optical fiber measuring device using phase difference |
摘要 |
The invention concerns an optical fiber measuring device, for example a gyrometer. The working of this device is independent of possible variations in the spectrum of the source. It includes a narrow, stable spectral filter which separates the incident flux. The modulation chain is slaved by a first detector (3). A second detector (23) receives the filtered flux. Its response is processed by a device (219) which supplies a signal that is a function of the spectrum of the light source (1).
