Title: Innovations of Louis St-Onge
Introduction
Louis St-Onge is a notable inventor based in Côte Saint-Luc, Canada. He has made significant contributions to the field of material analysis through his innovative patents. With a total of three patents to his name, St-Onge has developed methods that enhance the understanding of heterogeneous materials.
Latest Patents
One of his latest patents is titled "Method and apparatus for three-dimensional compositional mapping of heterogeneous materials." This invention utilizes laser ablation combined with spectrometric analysis to determine the composition of heterogeneous materials. By measuring the depth of an ablation crater at a target, it is possible to generate a compositional profile as a function of depth. Additionally, a three-dimensional profile can be created by depth profiling multiple craters. The depth measurement is conducted in situ and in real time, allowing for the evolution of composition to be measured effectively. An interferometric technique with a short coherence length light is one of the preferred embodiments for this measurement.
Another significant patent is "Method and apparatus for enhanced laser-induced plasma spectroscopy using mixed-wavelength laser pulses." In this invention, a sample of heterogeneous material is analyzed by directing a mixed-wavelength laser pulse at the sample to produce a plasma. The mixed wavelength pulse contains both shorter and longer wavelength components, and the composition of the material is determined from the emission spectrum of the plasma.
