Development of an Airborne Integrated Phase Doppler Interferometer/Imaging Probe for Accurate Cloud Droplet Size Distribution Measurement

Abstract

The Phase I effort investigated the feasibility of developing an optical probe based on phase Doppler interferometry (PDI) for reliable and accurate measurement of the cloud droplet size distribution from airborne platforms. The key features of this device are high accuracy and precision droplet sizing, large dynamic range, accurate concentration measurement throughout the entire instrument dynamic range, very low coincidence errors, and large counting volume.
