Holographic data from the prototype airborne digital holographic probe, HOLODEC 1
(Holographic Detector for Clouds), taken during test flights are digitally reconstructed to
obtain the size, three-dimensional position, and twodimensional profile of ice particles and
then ice particle size distributions and number densities are calculated using an automated
algorithm with minimal user intervention. The holographic method offers the advantages of a
well-defined sample volume size that is not dependent on particle size or airspeed, and …
