Abstract

Characterizing individual airborne particles in real time according to their absorption of optical energy at one or more wavelengths. The instrument can measure the two-dimensional angular optical scattering (TAOS) and/or the one-dimensional angular optical scattering (ODAOS) at one or more wavelengths. When two wavelengths are used, one is chosen to be on an absorption peak, the other is off of the absorption peak (preferably in the absorption valley).
