Optical fiber preform
WebThe structural properties of an optical fiber preform are directly transferred to the fiber state with the fiber actually becoming a scaled-down version of its parent.1 It is therefore conceivable to apply diagnostic procedures to the preform itself2 to evaluate its quality and eventual performance as a fiber. WebOct 19, 2024 · The optical fiber preform image at an angle of 0 angles is used as the preliminary screening image to detect defects in the optical fiber preform and open up storage space to record the number and height information H of the defect and the distance between the defect and the boundary M; 4. Track the defects and use the tracking …
