Inspection Method For Optical Fiber, Inspection Device For Optical Fiber, And Method For Manufacturing Optical Fiber Wound Bobbin
Abstract: This inspection method for an optical fiber (1) including an optical fiber bare wire (1N) and a light-transmitting coating layer (12) covering an outer peripheral surface of the optical fiber bare wire (1N) comprises: an irradiation step (S1) for irradiating, with illumination light (L) having directivity, an outer peripheral surface (30s) of a wound body (30) obtained by winding, in multiple layers, the optical fiber (1) around a bobbin (20); an image data generation step (S2) for receiving the illumination light (L) reflected by the wound body (30) and generating image data including at least a part of an image (IM) of the illumination light (L); and an inspection step (S3) for determining, on the basis of the image data, whether or not the image (IM) has a stripe pattern (SP) in which a state of the illumination light (L) repeatedly changes along a winding direction of the optical fiber (1).
