  • Patent number: 9798078
    Abstract: The present invention provides a filter composed of two layers of materials with different expansion coefficients. The difference between a length added to a whole section length of an outer low-expansion coefficient metal sleeve by a temperature change and a length added to a length of a whole section of high-expansion coefficient cylindrical coil spring arranged therein by the temperature change causes a stress-releasing or stress-increasing effect on the whole section of pre-tensioned high-expansion coefficient cylindrical coil spring arranged therein, so that a structure capable of compensating the wavelength shift of the fiber Bragg's grating filter caused by temperature by increasing or decreasing the refractive index is achieved.

  • Patent number: 9513111
    Abstract: An optical fiber sensing spring of the present invention includes a longer cylindrical tension coil spring, a shorter cylindrical compression coil spring and a longer cylindrical tension coil spring that are connected in series to form a spring having the same inner and outer diameters. A single-mode optical fiber manufactured with a long section of fiber grating is placed in the manufactured spring. This section of the fiber grating is tensed to two ends of the cylindrical compression coil spring having a predetermined gauge length, and the force applied is released.
