| 摘要： | Using an infrared Fourier transform spectrometer (IFTS) hyperspectral imager (HSI), measurements where made of a turbulent exhaust plume. Using these data, hyperspectral tomography algorithms were used to solve for the 3D temperature and species concentration spatial distributions. Turbulent effects were incorporated into the algorithms and the resulting solutions were compared directly to thermocouple temperature data collected throughout this exhaust flow. |
