摘要： An optical sensor system includes a multi-color pyrometer in optical communication with a component. The pyrometer generates signals at least partially representative of radiation received from the component and from soot particles. The system includes at least one processing unit coupled to the pyrometer. The processing unit is programmed to receive the signals and distinguish portions of radiation received between at least two wavelength bands. The processing unit is also programmed to determine that a first portion of radiation within a first of the wavelength bands is representative of a temperature of soot particles and that a second portion of radiation within a second of the wavelength bands is representative of a temperature of the component. The processing unit is further programmed to filter out signals representative of the first portion of the radiation.

摘要： A smart radiation thermometry system including a turbine component is provided. The thermometry system also includes at least one smart real time processing sub-system electrically coupled to at least one detector array via at least one high-speed multi-channel ADC. The at least one smart real time processing sub-system calculates temperature and emissivity of the turbine component based upon a computed radiance temperature, reflection correction and multi-wavelength algorithm.

摘要： A method of measuring fluid flow including the steps of providing a light source including at least one LED, providing an image detecting element and defining an illuminated measurement space with an optical element located between the measurement space and the image detecting element. The measurement space is located optically in-line between the light source and the image detecting element. The method further includes the steps of providing a fluid flow through the measurement space, the fluid flow including particles, and illuminating the measurement space with the light source to induce light extinction from the particles comprising shadow markers of the position of the particles within the fluid flow. The image detecting element is used to detect the shadow markers produced by the particles to record displacement of the particles as a function of time corresponding to movement of the fluid flow. In a further aspect, the light source includes plural LEDs emitting different colors.
