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

摘要

Presents a strategy for sizing aerosols and water droplets in airnusing multiwavelength and multisensor technology. The proposednoptical-microwave measurement method is based upon the assumptions thatnthe particles to be sized are spherical and traverse a uniform field ofnplane waves. The optical-microwave system with fixed differentialnfrequency shift f_m between two beams of different wavelengthnhas two microwave detectors and two detector receiving optics. Mie andnRayleigh theory are used in this analysis
