Summary on Grant Application Form |
Quantitative optical imaging techniques have revolutionised the analysis of flow systems such as fuel injectors and other sprays, combustors and chemic reactors, fog and clouds and biological systems. However most imaging techniques assume single scattering. Multiple scattering of the detected photons introduces an error that may be extremely serious in turbid systems. In the worst cases multiple scattering destroys all contrast in the image, as in the obscuring effect of fog. In spray measurement, the error due to multiple scattering has been largely ignored. A recent study by the author tackled the problem in sprays imaging for the first time. This proposal describes a programme of work building on that study and aimed at (1) producing flexible and validated computational tools for assessing the uncertainties and errors due to multiple scattering (2) producing a published database of calculations in typical situal and (3) assessing some potential methods for mitigating the effect of multiple scattering, to improve the accuracy of optical measurement techniques and 1 improve contrast and visibility in practical turbid systems, both in laboratory scale spray measurements and applications such as firefighting and underwater operations, powder handling and infra-red heat transport.
