Abstract
A method for evaluating a target, the target having a surface, includes pulsing a defined, energetic particle beam through the surface and into the target such that particle energy deposition from the particle beam is concentrated in a subsurface target volume within a target medium of the target. The deposited particle energy induces a thermoelastic expansion of the target medium in the target volume that generates a corresponding acoustic wave. The method further includes detecting the acoustic wave from the target medium.

A method for evaluating a target, the target having a surface, the method comprising:
- pulsing a defined, energetic particle beam through the surface and into the target such that particle energy deposition from the particle beam is concentrated in a subsurface target volume within a target medium of the target;
- wherein the deposited particle energy induces a thermoelastic expansion of the target medium in the target volume that generates a corresponding acoustic wave;
- and
- detecting the acoustic wave from the target medium.
A method for evaluating a target, the target having a surface, the method comprising:
- pulsing a plurality of X-ray beams through the surface and into the target such that the plurality of X-ray beams converge in a subsurface target volume within the target, wherein particle energy deposition from the plurality of X-ray beams is concentrated at the target volume in a target medium of the target;
- wherein the deposited particle energy induces a thermoelastic expansion of the target medium in the target volume that generates a corresponding acoustic wave;
- and
- detecting the acoustic wave from the target medium.
