Fiber-optic strain sensing is known for its ability to monitor large areas. However, most types of fiber-optic strain sensors require spectrum analysis instruments, which drastically increases the overall cost of sensor systems. In contrast, fiber-optic strain sensors such as Bragg-grating or Brillouin optical time domain reflectometers, have reliable structures that are commercially available. However, they are not widely used to support workers in high-risk construction sites.
