Ultrahigh Resolution Fiber-Optic Quasi-Static Strain Sensors for Geophysical Research
Zuyuan HE, Qingwen LIU, and and Tomochika TOKUNAGA
A review of our recent work on ultrahigh resolution optical fiber sensors in the quasi-static region is presented, and their applications in crustal deformation measurement are introduced. Geophysical research such as studies on earthquake and volcano requires monitoring the earth’s crustal deformation continuously wit

Application of Brillouin Optical Correlation Domain Analysis for Crack Identification in Concrete Structure
[in Chinese], and [in Chinese]
This paper investigates the application of distributed optical fiber strain sensors to civil engineering structures, because no other tool can satisfactorily detect the location of the unpredictable phenomenon. In fact, the locations of cracks in the concrete structure are unknown a priori; therefore, a fully distribut
