回転摂動の英語

これにより、長周期光繊維格子の製作時、予め光繊維に捻れを印加するか、或は光繊維を回転させながらUV光を照射して光繊維コアの屈折率を摂動させて光繊維の全長から見て等方的な屈折率の摂動を引き起こす。例文帳に追加

Thereby, when the long-period optical fiber grating is to be produced, the optical fiber 406 is preliminarily twisted, or while the optical fiber is twisted, the fiber is irradiated with UV rays so as to produce disturbance in the refractive index of an optical fiber core and to cause isotropic disturbance in the refractive index along the longitudinal direction of the fiber. - 特許庁
