Comment on “Aquifer Characterization Using Fiber Bragg Grating Multi-Level Monitoring System”
Response or Comment
Wang et al. (2022) describe the fiber Bragg grating (FBG) optical fiber transducer technology for pressure sensing in hydrologic testing applications, and in particular, for hydraulic tomography (HT) testing. As part of their Introduction section, Wang et al. describe attributes and published accounts of HT testing configurations with an alternative fiber-optic pressure-sensing technology using Fabry-Perot (FP) interferometry sensors or transducers. While such descriptions must be limited for space considerations, they should still be clear and correct—especially for the comparative presentation of optical fiber transducer technologies that are not yet widely used in hydrogeological applications (Leven and Barrash 2022).
