As a new energy source, hydrogen (H2) detection is a hot topic in recent years. Because of
the weak absorption characteristic, laser spectroscopy-based H2 detection is challenging. In …

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 …

In this paper, a differential quartz-enhanced photoacoustic spectroscopy (D-QEPAS) sensor
is reported. The differential photoacoustic cell (PAC) was used to generate the …

The disturbance-immune, fast response light-induced thermoelastic spectroscopy (LITES)
gas sensor based on out-plane vibration (OPV) mode employing micro Fabry-Perot cavity …

Due to its advantages of non-contact measurement and high sensitivity, light-induced
thermoelastic spectroscopy (LITES) is one of the most promising methods for corrosive gas …

A new temperature measurement method based on light-induced thermoelastic
spectroscopy (LITES) was demonstrated for the first time, to the best of our knowledge, in …

In this paper, we report on the performance of quartz tuning fork (QTF) based laser
spectroscopy sensing employing multiple QTFs. To avoid that resonance frequency …

In this Letter, a sensitive light-induced thermoelastic spectroscopy (LITES)-based trace gas
sensor by exploiting a super tiny quartz tuning fork (QTF) was demonstrated. The prong …

In this Letter, a hollow waveguide (HWG)-based light-induced thermoelastic spectroscopy
(LITES) gas sensing is proposed. An HWG with a length of 65 cm and inner diameter of 4 …

Infrared laser technology over the last decades has led to an increasing demand for optical
detectors with high sensitivity and a wide operative spectral range suitable for spectroscopic …
