Optical cavity type of sensor elements for a wide range of hydrogen gas detection

We have demonstrated a wide range of hydrogen gas detection from 200 ppm to 100% at room temperature by using optical cavity type of sensor elements with polarization interference. This explosion‐proof type of sensor element provides a hydrogen monitoring system in flammable environments for gaseous...

Zusammenfassung:	We have demonstrated a wide range of hydrogen gas detection from 200 ppm to 100% at room temperature by using optical cavity type of sensor elements with polarization interference. This explosion‐proof type of sensor element provides a hydrogen monitoring system in flammable environments for gaseous fuels.
