Abstract
The detection of trace gases is essential in various applications, from environmental monitoring and industrial process control to medical diagnostics. The need for high-sensitivity, compact, and costeffective gas sensing systems drives continuous advancements in sensor technology. Among optical sensors, photothermal spectroscopy (PTS) offers distinct advantages, detecting the indirect effects of thermal waves induced in the sample by exciting the molecules with a laser. More particularly, photothermal interferometry (PTI) uses interferometric methods, such as the Fabry-Pérot (FP) interferometer for the read-out.
