First Claim
Patent Images
1. A shock pressure gauge for measuring applied pressure in a laser shock peening device, said gauge comprising:
- a back-up disk;
a cap with an external surface and an internal surface, said internal surface facing said back-up disk, said gauge being operatively arranged to enable operative laser energy communication from said laser shock peening device to said cap; and
a pressure-sensing element disposed between said back-up disk and said cap.

Abstract
An apparatus for measuring the strength of a pressure pulse created from a laser peening device. The apparatus is reusable, and includes a pressure-sensitive medium, a back-up disk, and a cap, all disposed within a housing having a removable lid. All components of the apparatus are replaceable, thereby allowing an operator to utilize the apparatus more than once despite the harsh environment of laser peening.
