Based on Optical Time-Domain Reflectometry and Rayleigh scattering, fully automatic control mechanics-optics coupling test system was designed for model tests of crack sensing and the constitutive relation of crack sensing using distributed fiber sensor was investigated. Its initial sensing crack width attained 0.1 mm, dynamic sensing range reached 5.3 mm and positioning precision achieved 0.2 m. And also, semi-empirical formula was fitted from data.
