Multi-gas detection represents a suitable solution in many applications, such as
environmental and atmospheric monitoring, chemical reaction and industrial process …

Quantum technology is an emergent and potentially disruptive discipline, with the ability to
affect many human activities. Quantum technologies are dual-use technologies, and as such …

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 …

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 paper, an ultra-highly sensitive light-induced thermoelastic spectroscopy (LITES)
based hydrogen chloride (HCl) sensor, exploiting a custom low-frequency quartz tuning fork …

An integrated near-infrared fiber-optic photoacoustic sensing demodulator was established
for ultra-high sensitivity gas detection. The demodulator has capacities of interference …

The decomposed components analysis (DCA) is highly valued for potential faults diagnosis
in SF 6 gas-insulated power equipment (GIE). The current method and technology for …

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 high-sensitivity fiber-optic Fabry-Perot (FP) photoacoustic gas detection system with
properties of anti-electromagnetic interference and intrinsically safe was presented for …
