Two-Dimensional, Stereo, Particle Imaging Probe

Short Name or Variable Name

Two 128-photodiode linear arrays work independently as high-speed and high-resolution optical imaging probes. Captures two-dimensional images of particles passing through sample volume where laser beams overlap. The region where the beams overlap uniquely defines the depth of field (and thus the sample volume) for small particles. Particles as small as 10 microns are imaged at 200 m/s, significantly improving the determination of sample volume and sizing of small particles less than 100 microns. Data rates up to 13 MB per second, compressed into a binary file. It fits in a standard PMS 2D canister and uses standard wiring.


Measurements Provided: 

Cloud particle distribution, size, and images from 10 to 1280 microns at 10 micron resolution
