FIBRE-OPTIC INTERFEROMETRIC MEASUREMENT DEVICE COMPRISING A RING RESONATOR, GYROMETER AND INERTIAL ATTITUDE OR NAVIGATION UNIT COMPRISING SUCH A DEVICE |
摘要 |
A fibre-optic interferometric measurement device (100) intended to measure a physical parameter (QR), includes: a wide-spectrum light source (103); a SAGNAC fibre-optic interferometer (110), in which there propagate two counter-propagating light waves (101, 102) including measurement elements (1140) sensitive to the physical parameter that results in a non-reciprocal phase difference &Dgr;&phgr;&rgr; between the two light waves; and a detector (104) delivering an electric signal representative of the physical parameter. The measurement elements include a ring resonator (1143) in transmission mode including a first coupler (1141) and a second coupler (1142) respectively, which couple a first arm (111) and a second arm (112) respectively of the SAGNAC interferometer to the ring resonator, in such a way that the two light waves travel in opposing directions of travel (1143H, 1143AH). |
