Small Business Innovation Research/Small Business Tech Transfer
Novel Instrument to Measure Aerosol Fluorescence, Absorption, and Scattering, Phase I
Project Introduction
Picarro, Inc proposes to develop the first cavity ringdown spectroscopy (CRDS) system to measure fluorescence, absorption, and scattering properties of atmospheric aerosols in real-time and in-situ. These unique capabilities will enhance NASA?s studies of aerosol properties including single-scatter albedo, size distributions, and particle types. The fluorescence spectra will enable discrimination between biological and non-biological aerosols. The flight-deployable instrument will weigh less than 25 kg and have a measurement time resolution of 1 second. Our approach utilizes a high-finesse CRDS cavity to measure extinction and to enhance the scattering and fluorescence signals attainable using low power diode laser based light sources.
