FABRICATION METHOD OF MULTI-CORE FIBER BRAGG GRATING PROBE USED FOR MEASURING STRUCTURES OF A MICRO PART BASED ON THE CAPILLARY SELF-ASSEMBLE TECHNIQUE
Document Type and Number:
WIPO Patent Application WO/2016/138853
Kind Code:
A1
Abstract:
A fabrication method of the multi-core fiber Bragg grating (FBG) probe for measuring structures of a micro part based on the capillary self-assembly technique, wherein the diameter of the fiber (6) inscribed with FBG is reduced using a mechanical method or an etch method by the hydrofluoric acid; the fibers(6) inscribed with FBG, whose diameter has been reduced, are inserted into a tube(7) through its terminal with an inner taper angle; the FBG terminals of these fibers (6) are immersed into the UV adhesive (10) of a low viscosity and the UV adhesive (10) is raised in the gaps between the fibers (6); or the UV adhesive is dropped on the these fibers (6) and the capillary bridge between the fibers (6) is formed; a most compact structure of the fiber bundle is formed as a result of the capillary self-assembly; the fiber bundle is cured using a UV light and the multi-core FBG (11) is therefore formed; the terminal of the multi-core FBG (11) is polished with an optic fiber polishing machine and then a spherical tip is fabricated with the melting fiber method or the installation method of a micro ball; therefore, a multi-core FBG (11) probe can be achieved. The method features low crosstalk between signal of FBG, inexpensive and low insertion loss.
