Abstract (en)
[origin: WO2022087193A1] Disclosed herein are methods and apparatuses (100) for detecting defects in fiber-containing structures (110) using at least one defect detector including a projector (115) and an optical receiver (130) capable of measuring the cross-sectional diameter of the fiber- containing structures while in linear motion. Said cross-sectional diameter is calculated based on a reduction in an amount of light 135 detected by the optical receiver relative to the total amount of light (140) transmitted by the projector. Also disclosed herein are fiber-containing structures that have been subjected to the defect detection methods.
