Abstract (in Japanese) (See Japanese page) 
(in English) Distributed Fiber Optic Sensing is being utilized in construction projects to enhance safety and quality management. We have conducted research into strain sensing technology based on PNC-OFDR, which can instantly capture the strain distribution of civil structures. In this study, we have developed a field-friendly analyzer for on-site operation. We provide an overview of the commercially available analyzer and some application examples.
