Abstract
An optical fiber alignment method makes it possible to reduce the time required for alignment work for an optical fiber. This alignment method includes: an image acquisition step of acquiring an end surface image of an optical fiber; a measurement step of measuring arrangement data relating to a plurality of elements from the end surface image; a calculation step of calculating an amount of deviation of each of the plurality of elements from a target element arrangement from a correspondence relationship of the elements between the obtained arrangement data and reference arrangement data for element identification recorded in advance; and an alignment step of rotating the optical fiber around a central axis such that the obtained amount of deviation is reduced.
