Latest Patents
Among his latest patents, Howell has developed a method for the mitigation of optical signal noise using a multimode transmit fiber. This invention includes an apparatus designed to measure combustion parameters within the measurement zone of a gas turbine engine. The measurement zone is defined as the area between an outer casing and an engine component that has a reflecting surface. The apparatus features a laser that generates a transmitting beam of light at a specific wavelength, coupled with a multimode transmitting fiber. A transmitting optic is used to direct the beam into the measurement zone, where the reflecting surface is configured to provide a Lambertian reflection. Additionally, a receiving optic is positioned to capture this reflection, and mechanisms are included to average modal noise induced signal level variations within the multimode fiber.
Another significant patent involves time-synchronized tunable diode laser absorption spectroscopy (TDLAS) measurements of pressure and temperature in a gas turbine engine. This method utilizes absorption spectroscopy to determine rapidly variable gas parameters. It includes transmitting light from a synchronization light source to a synchronization detector, with the light being periodically interrupted by a moving mechanical part. The output from the synchronization detector generates a repeating time signal with variable phase delay, which is then used to control the timing of laser spectroscopy wavelength scans. This innovative approach allows for multiple spectroscopic scans to be averaged for improved accuracy.
