Phase optical-microwave method for sizing droplets in air. Theory and numerical treatment

Abstract

Presents a strategy for sizing aerosols and water droplets in air using multiwavelength and multisensor technology. The proposed optical-microwave measurement method is based upon the assumptions that the particles to be sized are spherical and traverse a uniform field of plane waves. The optical-microwave system with fixed differential frequency shift f/sub m/ between two beams of different wavelength has two microwave detectors and two detector receiving optics. Mie and Rayleigh theory are used in this analysis.<>
