Technical Note: The single particle soot photometer fails to reliably detect PALAS soot nanoparticles [PDF]
Atmospheric Measurement Techniques, 2012 The single particle soot photometer (SP2) uses laser-induced incandescence (LII) for the measurement of atmospheric black carbon (BC) particles. The BC mass concentration is obtained by combining quantitative detection of BC mass in single particles with

Laser-induced incandescence calibration via gravimetric sampling [PDF]
Combustion and Flame, 1996 Various beam imaging and/or sheet forming optics delivered light at 1064 nm from a pulsed Nd:YAG laser for use either as a beam of 3 mm radius or as a laser sheet. Imaging measurements were performed with a grated intensified array camera equipped with an ultraviolet f4.5 lens and a 40 mm extension tube.

Special Issue: Laser-Induced Incandescence [PDF]
Applied Physics B, 2011 Detection of nanoparticles is an area of particular interest for the scientific community. Nanoparticles are ubiquitous, i.e. carbonaceous nanoparticles, or soot, originating from a variety of anthropogenic combustion sources and biomass burning; they greatly reduce the air quality and affect the public health.

Laser-induced incandescence: detection issues [PDF]
Applied Optics, 1996 Theoretical predictions suggest that soot particle size and local gas temperature affect both the spectral intensity and the temporal evolution of laser-induced incandescence. A discussion of both the physical structure and the theoretical absorption models of soot aggregates is presented, suggesting that the soot particle size relevant to laser ...
