Our objective was to develop an airborne optical sizemeter for atmospheric water droplet characterization. We chose the ILIDS (interferometric laser imaging for droplet sizing) method. This paper details the acquisition method developed to implement the image processing and the experimental tests performed to validate the method. The purpose is to develop a strategy for real-time data analysis in order to obtain information on droplets size during flight; this work is included in the EUFAR project that is supported by the 7th Framework Program of the European Commission (FP7). © 2010 IOP Publishing Ltd.
