Fast Response Sensor for the Measurement of the Optical Properties and Carbon Content of Organic Aerosols

Abstract

In the Phase I studies the ability of a prototype instrument, the aerosol vaporization spectrometer (AVS) was evaluated for the ability to In the Phase particles by their incandescent signal. The instrument uses a diode pumped Nd:YAG laser at 1.06 mu wavelength to excite the particles. The scattering signal is monitored from all of the particles, and the black carbon particles absorb sufficient energy to incandesce, and this incandescence is measured by broadband and narrowband detectors. The work detailed in this report, conducted under the optional phase I funding is designed for an accelerated start on the Phase II developments. The electronic and optical components of the system have now been modeled and documented. The first phase of the data system has been implemented, and recording of particle spectra is underway.
