 | This program explored the potential of absorption techniques for low ppm, real time three-dimensional combustion diagnostics. Convolution, Fourier transforms and iterative algorithms have already been proven in x-ray absorption tomography and interferometric applications. They have been tested and compared for their ability to determine typical pollutant and radical concentrations as they appear in flames or exhausts. The effect of the number of scans has been analyzed for parallel beams. A ... |

 | This program explores the potential of absorption techniques for low ppm, real time 3-dimensional combustion diagnostics. IN the current phase of activity, a laser beam has been transformed into a sheet of light and made to converge on a 126-element array, with electronics suitable for repeatable 1.5 KHz scanning and data processing. Available memory modules (4K) allow for 34 successive slicings of a passing target within 20 milliseconds. In this ... |

| Absorption techniques are being applied to three-dimensional combustion diagnostics. By using multiagular scanning, the traditional 'onion-peeling' method can be extended from axisymmetrial flows to arbitrary distributions of radicals and pollutants in the flow. Since Scattering 'point' techniques are limited by their very small cross section, such an extension would be a step improvement in sensitivity, down to low radical concentrations. Convolution Fourier transforms and iterative algorithms have already been proven ... |

| The volume contains the proceedings of the Symposium on Interdisciplinary Aspects of Radiative Energy Transfer held in Philadelphia, Pennsylvania on 24-26 February 1966. The participation in the symposium turned out to be most important in those areas connected with high-speed shocks, stellar atmospheres and meteorology. The papers emphasized, in about equal numbers, the two main classical directions of radiative transfer: diagnostic techniques and energy exchanges. Topics of common interest to ... |
