Method and apparatus for detecting embedded material within an interaction region of a structure
First Claim
1. A detection system for use during irradiation of an interaction region of a structure with laser light, the structure comprising embedded material, the detection system comprising:
- an optical system for drilling a hole in the structure using the laser light, thereby exposing previously-unexposed embedded material within the interaction region;
an analyzer adapted to receive light from the interaction region, the analyzer adapted for analysis of the light from the interaction region for indications of exposure of the embedded material to air during the irradiation;
wherein the detection system is adapted to avoid damaging the irradiated embedded material upon detecting the exposure of the embedded material.

Abstract
A system and method processes a structure comprising embedded material. The system includes a laser adapted to generate light and to irradiate an interaction region of the structure. The system further includes an optical system adapted to receive light from the interaction region and to generate a detection signal indicative of the presence of embedded material in the interaction region. The system further includes a controller operatively coupled to the laser and the optical system. The controller is adapted to receive the detection signal and to be responsive to the detection signal by selectively adjusting the laser.
