  • Laser plasma spectroscopy apparatus and method for in situ depth profiling
    Patent number: 7440097
    Abstract: An in-situ laser plasma spectroscopy (LPS) system for automated near real-time elemental depth profiling of a target including: an optical source configured to generate an optical beam, wherein the optical beam is pulsed; an optical probe system configured to deliver the optical beam from the optical source to a surface of a target to generate an ablation plasma; a time resolved spectral detection system configured to generate time resolved spectral data from emission signals from the ablation plasma; and a data acquisition and processing system configured to acquire the time resolved spectral data to determine, in combination with predetermined calibration data, an absolute elemental concentration as a function of depth in near real-time.
    Type: Grant
    Filed: June 27, 2006
    Date of Patent: October 21, 2008
    Assignee: General Electric Company
    Inventors: Pamela King Benicewicz, Pavel Alexeyevich Fomitchov, Elena Rozier, John Ruediger Mader Viertl, Tymm Bradner Schumaker

  • Methods and apparatus for evaluating rotary machinery
    Patent number: 7064825
    Abstract: A method for determining a useful life applied to a coating on a surface of a component coupled to a rotatable member of a rotary machine. The method includes directing a laser across a surface of the component while the rotatable member remains coupled within an assembled rotary machine and measuring radiation emitted from the surface of the component.
