    Abstract: A temperature measurement system includes at least one temperature measurement probe. The at least one temperature measurement probe includes at least one hollow filament configured to emit thermal radiation in a predetermined and substantially continuous wavelength band at least partially representative of a temperature of the at least one hollow filament. The at least one hollow filament has a first diameter and a first emissivity. The at least one temperature measurement probe also includes at least one thin filament extending within at least a portion of the at least one hollow filament. The at least one thin filament is configured to emit thermal radiation in a predetermined and substantially continuous wavelength band at least partially representative of a temperature of the at least one thin filament. The at least one thin filament has a second emissivity and a second diameter less than the first diameter.

    Abstract: An apparatus for insertion through an opening in an outer casing of a gas turbine engine and inspection of internal turbine components at elevated temperatures having an optical sight tube configured to optically communicate with an interior of gas turbine engine via a distal end disposed at the interior and a proximal end disposed exterior of the internal turbine components and defined by a first longitudinal wall, at least one lens at the distal end of the optical sight tube adjacent to the longitudinal wall; and at least one longitudinal cooling groove in the longitudinal wall for flowing a cooling medium from a location external to the turbine to cool the optical sight tube at a location at least adjacent the distal end.

    Abstract: A temperature measurement system includes a plurality of filaments. The plurality of filaments are configured to emit thermal radiation in a relatively broad and substantially continuous wavelength band at least partially representative of a temperature of the plurality of filaments. A first and second portion of the filaments has a differing first and a second diameter and/or emissivity, respectively. The system also includes a detector array configured to generate electrical signals at least partially representative of the thermal radiation received from the filaments. The system further includes a controller communicatively coupled to the detector array configured to transform the first electrical signals to a first temperature indication at least partially as a function of the first diameter and/or first emissivity and transform the second electrical signals to a second temperature indication at least partially as a function of the second diameter and/or emissivity.

    Abstract: A multi-color pyrometry imaging system for a high-temperature asset includes at least one viewing port in optical communication with at least one high-temperature component of the high-temperature asset. The system also includes at least one camera device in optical communication with the at least one viewing port. The at least one camera device includes a camera enclosure and at least one camera aperture defined in the camera enclosure, The at least one camera aperture is in optical communication with the at least one viewing port. The at least one camera device also includes a multi-color filtering mechanism coupled to the enclosure. The multi-color filtering mechanism is configured to sequentially transmit photons within a first predetermined wavelength band and transmit photons within a second predetermined wavelength band that is different than the first predetermined wavelength band.
