Abstract
A fusion splicer includes an irradiation unit to irradiate an optical fiber with first wavelength light and second wavelength light; a light receiving unit; a processing unit to extract first feature data from first luminance information based on the first wavelength light and to extract second feature data from second luminance information based on the second wavelength light; a determination unit to determine whether the first feature data and the second feature data are within a predetermined range; and a drive unit to move one optical fiber on the basis of the luminance information from which the feature data is extracted so as to arrange the axes of the optical fibers in a predetermined positional relationship when the feature data is determined to be within the predetermined range. The processing unit extracts the second feature data when the first feature data is not within the predetermined range.
