摘要: | The present invention provides a fiber Bragg grating system, which employs a linear-cavity fiber laser scheme to develop a high resolution sensor system. The fiber Bragg grating sensor device is located in one end for fiber laser reflecting, and in the other end is a fiber loop mirror. It forms a linear-cavity fiber laser scheme basis. The end for laser output parallel connecting with two fiber Bragg grating filters. Because of the spectrum shift of the fiber Bragg grating sensor when temperature changed, it may detect the optic power reflectivity for the variation of the temperature. Furthermore, it can resolve the temperature up to 10.sup.-4.degree. C. theoretically and can be applied for strain and temperature sensing with high precision. |
