Multiple Reflection Techniques Used to Measure and Model a British Cannon Recovered from the Battle of Yorktown

Abstract

A British cannon recovered from the Battle of Yorktown had to be recorded completely – every external surface, and the bore from breech to muzzle – without touching a fragile, conserved artifact. Marcie Renner of The Mariners' Museum and Steve Hand of Maglev describe the significance and history of the gun, the scope of the measurement, the set-up and control network built around it, and the multiple-reflection technique that let the scanner see down the bore. The talk is candid about the problems met and the solutions found, and closes on the data processing and the finished model.
