Size distribution of solids suspended in water
Dynamic Light Scatter is used to determine a histogram of particle size (anticipated range 0.5 to 50um)

A sample of the aquaculture water is transferred into a small sample chamber. The chamber is illuminated using low cost pulsed diode lasers, resulting in light scatter. A camera synchronized with the laser timing views the scattered light and records the speckle images. These speckle pattern data are then processed on single board computers or FPGA's to tell us of the range of particulate sizes suspended in the water.

The processing must make use of training data sets previously collected from imaging known sample sizes created by either by sequential particulate filtering or by adding known size beads.
