ABSTRACT:
While a plastic optical fiber (POF) strand is guided by guide pulleys toward a winding machine, an internal defect in the POF strand is detected by a defect detection apparatus. The defect detection apparatus includes at least one light illumination device, at least one imaging device and at least one defect detection unit. The light illumination device illuminates the POF strand, and the imaging device takes an image of the POF strand and outputs signal to the detection unit.
