2D Stereo Probe
The two-dimensional stereo probe captures images of cloud particles at a resolution of 10 microns per pixel. The images are obtained as particles pass through the beams of two 128-photodiode linear arrays that intersect optically at the center of the probe's sample area. Particle inter-arrival times are used to reject fragments from shattered ice particles. This instrument is one of several cloud probes used during ISDAC in April 2008. Photo provided by Paul Lawson.
