Remote, early-time acoustic impact Doppler inspection
First Claim
1. A method for nondestructive analysis comprising:
- measuring a distance between an acoustic source and each of the points to be analyzed (pixels) on the surface of the object;
defining an optimization using the distance measurements;
acoustically bombarding the object at each target pixel;
recording and measuring the object'"'"'s surface response at each pixel;
processing the surface response measurements to account for extraneous information;
using the calculated optimization to generate the early-time line-up of the recorded measurements; and
analyzing this processed information using the generated early-time line-up to image the internal structure object.

Abstract
A method for nondestructive analysis is disclosed. The method includes measuring a distance between an acoustic source and each of the points to be analyzed (pixels) on the surface of an object. An optimization is then defined using the distance measurements. Thereafter, the object at each target pixel is acoustically bombarded, and the surface response at each pixel is recorded and measured. Optionally, the surface response measurements may be processed to account for extraneous information. The calculated optimization may then be used to generate the early-time line-up of the recorded measurements, and the processed information may be analyzed using the generated early-time line-up to image the internal structure object.
