| Abstract(in English) | Effective spatial resolution enhancement method for distributed strain measurement by BOTDR is proposed. According to theoretical analysis, it is proved that the apparent strain x_p observed in an optical fiber partially adhered. to a structure is proportional to the true strain a, whose ratio r=x_p/a coincides with the ratio of the adhered length to the spatial resolution defined by the optical pulse width on condition a is small enough, and it is verified experimentally. |
