Beschreibung
Zusammenfassung:	A circular rod optical defect detecting apparatus and a method thereof are provided to detect the defect of the surface of a wire rod by receiving light, reflected in the surface of the wire rod, with an optical sensor. A lighting unit irradiates light having a circular plane shape. An optical sensor(13) produces an optical signal by receiving light reflected from a circular wire rod(2) and converts the generated optical signal into a video signal. A signal processing unit(11) receives the video signal from the optical sensor and acquires the surface information of the circular wire rod.
