Patent attributes
A system and method for performing laser plasma spectroscopy on a surface of a component, particularly to detect, analyze, and determine the extent of deposit build up on turbomachine components protected by coatings that are susceptible to damage from infiltration of deposits. The system includes a laser energy source and a probe interconnected with the laser energy source to receive a laser beam therefrom and then direct the laser beam onto the surface of the component and scan an area of the surface while the component remains stationary. The probe is further configured to collect radiation emitted from a laser-induced plasma generated by the laser beam at the surface of the component. The system is further equipped to transmit the radiation from the probe and spectrally analyze the radiation.
