Infrared laser-absorption spectroscopy (IR-LAS) sensors play an important role in
diagnosing and characterizing a wide range of combustion systems. Of all the laser …

Optical imaging techniques are ubiquitous for the resolution of non-uniformities in gas flows.
Planar imaging techniques such as laser-induced fluorescence are well established and …

Laser absorption spectroscopy (LAS) has been rapidly developed and widely applied to
combustion diagnosis in recent decades. As a cost-effective tool for measuring multiple …

Tunable diode laser absorption spectroscopy (TDLAS) has become a proven method of
rapid gas diagnostics. In the present review an overview of the state of the art of TDL-based …

This work aims to develop a fan-beam tomographic sensor using tunable diode lasers that

The design and use of two-color tunable diode laser (TDL) absorption sensors for
measurements of temperature and H 2 O in a rotating detonation engine (RDE) are …

We present broadband dual frequency comb laser measurements of pure H 2 O absorption
(natural isotopic abundance of 99.7% H 2 16 O) from 6600 to 7650 cm− 1 (1307–1515 nm) …

Laser absorption spectroscopy (LAS) is a promising diagnostic method capable of providing
high-bandwidth, species-specific sensing, and highly quantitative measurements. This …

We present a tunable diode laser spectrometer with a novel, rapid time multiplexed direct
absorption-and wavelength modulation-spectroscopy operation mode. The new technique …
