Embodiment Construction
[0023] The present invention will be further introduced below in combination with specific embodiments.
[0024] Such as Figure 2 ~ Figure 3 Shown is a schematic structural view of the optical fiber sensor of the present invention, as can be seen from the figure, the optical fiber sensor includes a bare optical fiber 1 and a package body 2, the bare optical fiber 1 is packaged in the package body 2 along the central axis of the package body, and the package body on both sides of the bare optical fiber There are symmetrical side holes 3 on the top, the center of the bare optical fiber and the centers of the holes on both sides are on the same line, and guide grids 4 are arranged at intervals along the axial direction and in the direction of the center line between the two symmetrical side holes.
[0025] The guide gratings in this embodiment are evenly spaced between the side holes, and the guide gratings at the corresponding positions between the holes on both sides are alter...
