Abstract Fabry–Perot (F–P)-based phase demodulation of heterodyne light-induced
thermoelastic spectroscopy (H-LITES) was demonstrated for the first time in this study. The …

Methane (CH 4) is a greenhouse gas as well as being flammable and explosive. In this
manuscript, quartz-enhanced photoacoustic spectroscopy (QEPAS) and heterodyne QEPAS …

In this Letter, two novel, to the best of our knowledge, quartz tuning forks (QTFs) with
trapezoidal-head and round-head were designed and adopted for quartz-enhanced …

A highly sensitive light-induced thermoelectric spectroscopy (LITES) sensor based on a
multi-pass cell (MPC) with dense spot pattern and a novel quartz tuning fork (QTF) with low …

A novel dual-frequency modulated heterodyne quartz-enhanced photoacoustic
spectroscopy (DFH-QEPAS) was demonstrated for what we believe to be the first time in this …

A highly sensitive carbon dioxide (CO_2) sensor based on light-induced thermoelastic
