Grahic Jump Location
Schematic of Apparatus for Particle Cloud Generation System
Grahic Jump Location
SEM micrograph of a two-hour old Carbon particle cloud at magnification 2000. β=0.62 m−1 at 1064 nm. Inset shows magnification of 10,000.
Grahic Jump Location
Normalized particle population distribution of two particle clouds, β=1.55 m−1 and β=0.62 m−1 at 1064 nm. The distribution is a composite of scans at magnifications of 10,000, 2000 and 500.
Grahic Jump Location
Experimental apparatus for measurement of optical properties
Grahic Jump Location
Linear extinction coefficient vs. particle mass loading at λ=532 nm. The number density at a mass loading of 1 g/m3 is 1.5⋅1014 particles, and Ke=8.25
Grahic Jump Location
Measured and predicted scattering phase function at 532 nm and 1064 nm. Mie theory results are based on the full particle population distribution, including agglomerates. Error bars represent 95% confidence. (a) 532 nm parallel polarization. (b) 532 nm perpendicular polarization. (c) 1064 nm parallel polarization. (d) 1064 nm perpendicular polarization.
Grahic Jump Location
Effect of the agglomerates on the scattering phase function for perpendicular polarization, β=1.0 m−1. The full particle population distribution includes agglomerates, and the truncated distribution includes primary particles only (diameter less than 1 μm).
Grahic Jump Location
Spectral dependence of phase function for perpendicular polarization at β=0.90 m−1.
Grahic Jump Location
Spectral dependence of the scattering albedo at single scattering conditions. Error bars represent 95% confidence. Data for acetylene is from 1922. Data for toluene is from 22.
