We summarize recent studies on performance improvement in the correlation-based continuous-wave technique for optical fiber distributed strain measurement using Brillouin scattering, that had been proposed previously. The correlation-based technique enables the spatial resolution of 1 cm, which is difficult for conventional sensing techniques using Brillouin scattering to achieve. Though the correlation-based technique left a problem with measurement range, we have proposed methods to overcome it with keeping high spatial resolution. In addition, we verified usefulness of the technique for smart materials by measuring strain distribution along surface of a ring structure.
