Abstract: A system has been developed for measuring the distance between cloud droplets along the flight path with an airborne optical particle counter. This technique resolves separation distances as small as 0.2 mm at a typical ...

Abstract: The design, laboratory calibrations, and flight tests of a new optical imaging instrument, the two-dimensional stereo (2D-S) probe, are presented. Two orthogonal laser beams cross in the middle of the sample volume. Custom, ...
