FIBER-OPTIC DETECTION DEVICE AND METHOD FOR OPERATING SUCH A FIBER-OPTIC DETECTION DEVICE

摘要

The invention relates to a fiber-optic detection device (10), comprising at least one fiber (12) that is designed as a light guide, which has at least one first fiber element (14) having a first slow polarization axis (16), and at least one second fiber element (20) adjoining the first fiber element (14) in the longitudinal extension direction (34) of the fiber (12) having a second slow polarization axis (22), which in the circumferential direction of the fiber (12) is arranged offset from the first slow polarization axis (16), further comprising at least one sensor tandem (36), which has at least one first fiber bragg grating (38) that is written into the first fiber element (14), and at least one second fiber bragg grating (40) that is written into the second fiber element (20), and which is designed to detect, at a corresponding measuring point (M), a temperature prevailing at the measuring point (M), and to detect at least one load acting on the fiber (12) at the measuring point (M).
