  • Abstract
    This paper is described how FBG and OFDR can be combined to cover a greater number of locations by using FBGs with identical characteristics in combination with FBGs with different reflection wavelengths. We report on our basic experiments on multi-point strain measurements with a real-time measurement system. It is shown that this system can determine the reflection wavelengths from multiple FBGs with the same reflection wavelength simultaneously every 4 seconds.
