Latest Patents

One of her latest patents is a "Fabrication method of multi-core fiber Bragg grating probe used for measuring structures of a micro part based on the capillary self-assemble technique." This innovative method involves reducing the diameter of the fiber inscribed with FBG using mechanical or etching methods. The fibers are then inserted into a tube, and the FBG terminals are immersed in a low-viscosity UV adhesive, allowing for the formation of a compact fiber bundle through capillary self-assembly. The resulting multi-core FBG probe features low crosstalk between signals and minimal insertion loss.

Another notable patent is the "Method and equipment for dimensional measurement of a micro part based on fiber laser with multi-core FBG probe." This method utilizes a multi-core FBG probe to transform two-dimensional or three-dimensional contact displacement into spectrum shifts with high sensitivity. The FBGs in the probe serve as a wavelength selection device for the fiber laser, enabling precise measurement of contact displacement through wavelength changes.
