Redundant Ballistic Chronograph Configuration for Body Armor Testing



Michael A. Riley, Nicholas G. Paulter Jr., Dwight D. Barry


A new configuration of the light screen pairs used in a redundant ballistic chronograph is described. This configuration complies with current ASTM International and National Institute of Justice requirements for measuring the ballistic performance of body armor. Although it currently requires dismantling the commercially available light screens and installing them on custom-made mounting frames, the overall configuration is simpler to arrange and to obtain separation uncertainties than the conventional configuration that uses separate mounting frames.
