    Abstract Reading of the central fringe in absolute deformation measurement using white light fiber-optic interferometer (WLFOI) is proposed through introducing the second broadband source and a zero sensing arm. The zero sensing arm is a reminder about the initial position that have to be lost during the deformation. The second source is used to form a synthesized equivalent wideband source that, in general, is not available commercially. This combined source could simplify the central fringe identification. The design can carry out a good balance between the reading speed and precision in the absolute deformation measurement by WLFOI. A preliminary experiment confirms its efficiency.
