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.<>

相光微波法测定空气中液滴的大小。理论与数值处理
提出了一种利用多波长和多传感器技术测定空气中气溶胶和水滴大小的方法。所提出的光微波测量方法是基于待测粒子为球形并穿过均匀平面波场的假设。在不同波长的两束光束之间具有固定差频移f/sub m/的光微波系统具有两个微波探测器和两个探测器接收光学器件。在这个分析中使用了米理论和瑞利理论。
