The Small-Angle Light Scattering Spectral Analyzer (SALSSA) is a proof-of-concept instrument developed to measure the size of free-flowing liquid drop aerosol particles ranging from 5-50 micrometers in diameter. The design centers around conventional angular light scattering methods. Two-dimensional scattering patterns for individual particles are measured in two wavelengths, i.e., two-colors, simultaneously using a unique optical design. By analyzing specific features in the patterns, it is possible to determine the particle size.
