The centrally staged combustor is an effective way to reduce pollutant emissions. However,
combustion instability is one of the prominent and unavoidable problems for lean premixed …

Non-contact and real-time measurements for species concentration and temperature with
high-time resolution in practical combustion environments are desired. A laser absorption …

The tunable diode laser absorption spectroscopy (TDLAS) has been employed in various
fields successfully. However, most current TDLAS sensors have low spatial resolution, which …

To achieve the 2-D nonintrusive measurements of temperature and species concentration in
the combustion field, a new framework, combining calibration-free wavelength modulation …

In the present paper, the performances of an approach based on continuous wavelet
transform to demodulate wavelength modulation spectroscopy harmonic signal (CWT-WMS) …

We studied the boundary layer effects on flame temperature measurements using line-of-
sight (LOS) absorption spectroscopy. The primary objective is to quantify the measurement …

The development of temperature sensors with ultra-fast response, high sensitivity, and wide
range of temperature is of important academic value for the study of flame structure and …

Abstract Wavelength Modulation United Absorption Spectroscopy (WM-UAS), which is
virtually an extension of Wavelength Modulation Spectroscopy (WMS), for measuring multi …

This article proposes a frequency-division multiplexing (FDM) laser dispersion spectroscopy
(LDS) method to implement high-precision water vapor temperature measurement in a …

Energetic materials have extremely high volumetric and specific energy densities, making
