From wavelength-based sensing fundamentals to ultra-weak FBG arrays and high-density signal interrogation,this technology stack explains how optical signals are translated into precise, scalable, and reliable physical measurements.
Where to sense? What optical effect to use? How to interrogate it? What physical quantity to recover? Where to apply the result?
Five practical questions turn a crowded field of acronyms into a technology route you can understand.
