I explored FBG sensors early on and they are very cool -- I was aiming for a less expensive and more robotics-oriented application. Something that can be seamlessly integrated into a design at a lower level without the complexity of FBG technology.

I think you made the right choice. You've come up with a great sensor topology. FBGs are good, but there's so much to them that is just infuriating. I ended up late in my optics work spending most of my time finding ways to avoid them.
