Close-up of the sample area.  The dimensions of the area are ~1in.x.75in.x1.25in.  The holes you see in the cylinder are for balancing.

The underside of the rotating cylinder.  A photointerrupter was mounted to a platform from noted hole.  The photointerrupter will be used to trigger a strobe light so that we can precisely time/delay video capture.  (NOTE TO SELF include link to code for syncing PI and Magnet poles)
