Fiber optic white-light interfreometry is one of the unique measurement and sensing technology in the fiber optic research field. It is one of typical achievement application branches of fiber optic multidisciplinary research, such as broad-band light coherence characteristics, high precision deformation absolute measurement, waveguides components structures and reflectivity properties testing, cross-coupling between polarization states evaluation for fiber optic gyro, as well as low-coherence tomography technology for tissue and clinical diagnosis in medicine. A brief description about the white-light interfreometry and its development in the past several tens years is given. From the view of demands of market and the intrinsic rules of the technology development, the driving dynamics mechanisms of the technique is analyzed. Finally, the developing trend and forecast of this technology is pointed out.
