Design, Calibration, and Application of a Wide-Range Fiber Bragg
By connecting the snake spring desensitization mechanism in series with the FBG strain sensor, large structural strain is converted into a large strain in the snake spring and a smaller strain in the FBG,
Strain gradient sensor with high accuracy using cascaded fiber Bragg
This work proposes a novel strain gradient sensor based on fiber Bragg grating (FBG) technology. The sensor comprises M cascaded uniform FBGs (UFBGs) uniformly distributed along
Braided Fabrication of a Fiber Bragg Grating Sensor
We aimed to combine three-dimensional (3D) braiding processing with the optical Bragg grating sensor''s accurate metrology.
Strain Measurement with Fiber Bragg Grating Sensors
To write the Bragg grating into the fiber core the fiber must first be dismantled of the coating and afterwards newly coated. This process has to be done very thor-oughly, otherwise the mechanical
