Abstract
This coating condition detection method according to one embodiment uses a simple device structure to detect the coating condition of a resin layer of a coated fiber. Under the coating condition detection method, an imaging optical system including a reflection mirror having a guide hole through which the optical fiber passes is prepared, and the imaging optical system is disposed so as to cause an object plane conjugate with an imaging plane to intersect the optical fiber that has passed through the reflection mirror and forms an image of light released from the optical fiber on the imaging plane to detect intensity of light at each point on the imaging plane with the intensity of light associated with information on a corresponding position on the object plane.
