The objectives of this paper are twofold. First, the paper developed an improved algorithm to perform light scattering calculations by coated spheres. The improved algorithm was implemented in FORTRAN90 as a subroutine to allow flexible application o

Gas-temperature measurements in the combustion zone of a high-pressure gas-turbine-combustor sector rig were made with a Fourier-domain mode-locked laser using wavelength-agile absorption-spectroscopy techniques. These measurements are among the firs

This paper describes the application of the simulated annealing technique for the simultaneous retrieval of particle size distribution and refractive index based on polarization modulated scattering (PMS) measurements. The PMS technique is a well-est

At night, long-haul truck drivers rest inside the cabins of their vehicles. Therefore, the in-cab air quality while air conditioning (A/C) is being provided can be a great concern to the drivers’ health. The effect of using different A/C methods [t

Using a novel Fourier-domain mode-locking (FDML) laser scanning 1330–1380 nm, we have developed a gas thermometer based on absorption spectroscopy that is appropriate for combustion gases at essentially arbitrary conditions. The path-integrated mea

Wavelength-agile laser sources enable continuous monitoring of multiple spectral features, and are of high interest for spectroscopic sensing of combustion processes. Here, we present a tunable external-cavity diode laser (ECDL) based on a rapidly vi

We present a novel method for low noise, high-speed, real-time spectroscopy to monitor molecular absorption spectra. The system is based on a rapidly swept, narrowband CW Fourier-domain mode-locked (FDML) laser source for spectral encoding in time an

An external cavity laser has been designed for rapid but stable wavelength-tuning. To enhance the tuning stability, cavity modes are suppressed by rapidly changing the cavity length as part of the wavelength-scanning mechanism. The ~ 27 cm cavity len

This paper demonstrates the potential for fast absorption spectroscopy measurements in diesel-engine exhaust to track H2O concentration transients. Wavelength-agile absorption spectroscopy is an optical technique that measures broadband absorption sp

A sensor is demonstrated to characterize soot aggregates based on polarization modulated scattering. Comparison with other techniques shows promising agreement, and extension of the sensor to 1- or 2-dimensional soot imaging is discussed.
