Abstract:
A method and apparatus for measuring the quality of a laser peening process, which includes a test element, a mount for the test element, wherein the test element is mounted
at a preselected point in the anticipated path of a laser pulse, the laser pulse irradiates the test element, the deflection of the test element is measured in the direction
substantially perpendicular and away from the impacted surface of the test element, and the deflection measurement is compared to a previously generated chart showing the
relationship between characteristics of test elements and desired material properties.
