Title:
フローティングクランプ機構およびフローティングクランプ
Document Type and Number:
Japanese Patent JP4217765
Kind Code:
B2
Abstract:
To provide a clamp that causes no positional deviation of an optical fiber in the process of forming a fiber grating by irradiating the optical fiber with a ultraviolet laser beam through a phase mask.
In a conventional clamp, an optical fiber is firmly fixed. In this invention, for the purpose of providing the optical fiber with the degree of freedom, it is held through an elastic body comprising a spring and brought into a floating state, making the spring absorb positional deviation due to thermal expansion/contraction of the optical fiber or due to vibration from the outside, so that the position of the fiber grating is always automatically corrected.
