A simple fiber-optic pin for detecting a shock-wave front

A simple fiber-optic pin for detecting a shock-wave front has been developed. The pin has a simple structure, which consists of a graded index optical fiber and a glass capillary. The performance of the optopin has been confirmed with copper targets at a shock compression of about 70 GPa using a two...

Description
Summary:A simple fiber-optic pin for detecting a shock-wave front has been developed. The pin has a simple structure, which consists of a graded index optical fiber and a glass capillary. The performance of the optopin has been confirmed with copper targets at a shock compression of about 70 GPa using a two-stage light gas gun. The shock velocity in copper was determined by these pins within error of about 1% (a few nanoseconds) compared with well-known Hugoniot data.
