1. 2D-S Participation in RACORO Brad Baker, Paul Lawson and Qixu Mo

2.  2D-S Features  Examples of Quicklook IOPshare 2D-S Products  Data Place in Final Archives. Outline

3.  Custom 128-photodiode array/front end with ~ 10 times the response speed of older probes (smaller 50  m pixels on the array).  10  m particles imaged at 170 m s -1 (front end up to 233 m s -1 )  Two independent imaging probes in one instrument provide stereo images of some particles and measurement redundancy  Large Sample Volume: 3 times the 2D-C Sample Volume

4. Example Showing how 2D-S Particle Inter- arrival Times are used to Remove Shattered (and Splashed) Images

5. Example of Correcting out-of-focus “Donuts”
