Legacy Theses & Dissertations (2009 - 2024)
Compositional analysis of gases in real time is important for many industries. Traditionally, it was done with online sensors such as thermal conductivity detectors or analytical methods such as gas chromatography. Fiber Bragg grating (FBG) sensors have demonstrated unique advantages in gas sensing. This dissertation focuses on the designing of a thermal modulation system that can properly functionalize FBG sensors, and the building of a sensing system that can perform non-specific gas compositional analysis in real time for pure gases and binary gas mixtures.
