    • 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.

    • A system for on-line optical monitoring of a gas turbine engine includes a viewport into a combustor of the gas turbine engine and an optical filter optically coupled to the viewport. The optical filter is configured to receive broad wavelength band thermal radiation from an interior surface of the combustor while the gas turbine engine is in operation, to substantially block wavelengths of the broad wavelength band thermal radiation emitted and/or absorbed by a flame and/or by exhaust gas within the combustor, and to output narrow wavelength band thermal radiation from the interior surface of the combustor. The system also includes a detector array in optical communication with the optical filter. The detector array is configured to receive the narrow wavelength band thermal radiation and to output signals indicative of a two-dimensional intensity map of the narrow wavelength band thermal radiation.
    • 用于燃气涡轮发动机的在线光学监测的系统包括进入燃气涡轮发动机的燃烧器的视口和与该视口光学耦合的光学滤波器。 光学滤波器被配置为在燃气涡轮发动机运行时从燃烧器的内表面接收宽波长带的热辐射,以基本上阻挡由火焰和/或火焰发射和/或吸收的宽波段的热辐射的波长 通过燃烧器内的废气,并且从燃烧器的内表面输出窄波长带的热辐射。 该系统还包括与光学滤波器光学通信的检测器阵列。 检测器阵列被配置为接收窄波长带的热辐射并输出指示窄波段热辐射的二维强度图的信号。
