Two-Dimensional, Stereo, Particle Imaging Probe

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 imaged at 200 m/s. Greatly improved determination of sample volume and sizing of small particles less than 100 microns. Data rates up to 13 MB per second, compressed into binary file.
