Latest Patents
One of Leonard's latest patents is a method and apparatus for remotely measuring sub-surface water. This invention allows for the remote measurement of the sub-surface temperature of a body of water, such as an ocean, by directing a laser beam into the water and analyzing the Raman backscatter produced. The information obtained from the Raman backscatter is processed to indicate the water temperature at various depths. Precise temperature measurements can be achieved by detecting and measuring the polarization ratio at different wavelength intervals throughout the Raman band.
Another significant patent by Leonard involves a high-powered laser. In this invention, a gaseous mixture is heated to a specific temperature and pressure to provide a large energy content. The mixture includes a polyatomic gas, such as carbon dioxide, and at least one auxiliary gas, such as nitrogen. This setup allows for population inversion in the chamber, enabling the optical resonator to define a light path beam through the gaseous medium.
