Abstract
A method for estimating an orientation around a central axis of an optical fiber includes radiating light from a light source toward a side surface of the optical fiber, capturing an image of the side surface of the optical fiber by receiving the light transmitted through the optical fiber at a plurality of pixels disposed along a direction intersecting the central axis of the optical fiber, generating a luminance profile for the optical fiber based on a luminance value of light received by the plurality of pixels, and estimating an orientation around the central axis of the optical fiber using the luminance profile.
