METHODS FOR ESTIMATING OPTICAL FIBER ORIENTATION AND METHODS FOR MANUFACTURING OPTICAL FIBER COMPONENTS

Abstract

The invention relates to a method for estimating the orientation around the central axis of an optical fiber, consisting of a light-projection step from a light source onto the side surface of the optical fiber, capturing an image of the side surface of the optical fiber by collecting the light transmitted through the optical fiber at pixels arranged along the direction intersecting the central axis of the optical fiber, generating a luminance profile for the optical fiber based on the luminance values ​​of the light collected by the pixels, and estimating the orientation around the central axis of the optical fiber using the luminance profile.
