Future work will focus on the use of multiple frequencies so that both concentration and size distribution can be ascertained.  Field implementation will also be an important topic.

Currently, we are developing software using a DSP board (Digital Signal Processing).  This board collects the data, performs an FFT, and condenses the reuslts before sending the data back to the host computer for storage.  This makes it easier to process data to another source.

Additionally, we will improve upon the design of the Goodwin creek raft and control of its software.
