Not quite the same thing, but this reminds me of DAS using fiber optic cable for various acoustic sensing tasks--basically as an alternative to geophones/hydrophones. There have been a number of papers using transoceanic fibers for various monitoring tasks. That is also used for various industrial applications, e.g. for strain sensing by Luna Innovations. I know that Schlumberger has various patents on fiber-optic se…

Yeah initially doing literature review was a bit daunting because of all this existing work, especially FBG-type sensors, but this idea is so fundamentally simple that its been mostly bypassed by the smarter minds

Very beautiful research and thorough documentation. I initially wanted to comment that this looks a lot like time-domain reflectometry on a conceptual level - but as Cindy Harnett seems to be your advisor, you probably know that already :)

Paul, what an amazing project, this is what hacking is all about. Congratulations! Definitely try to explore the commercial side of your invention. It wouldn't hurt to talk to an IP lawyer, if you're still in Uni they usually have people there doing this and you can just go talk to them, free of charge (for you!). I'm generally against the idea of patents, mainly because of people who came to know to game the system…

Maybe I'm not understanding the blog post so bear with me. Isn't what he is described what a time domain reflectometer does? [1]. I mean that's what it's used to detect breaks or kinks in fiber optics cables. The same tech is used to detect problems in civil infrastructure with embbeded fiber optics.
