Abstract
In a previous publication a laser shadow technique for the quantitative investigation of turbulent flow has been introduced. Only simple two-dimensional flow fields have been considered for this purpose. In the present paper a method is provided that allows the application of this laser shadow technique to axisymmetric flow fields. The basic principle invoked is the Abel transform which has e.g. been applied extensively to determine the local emission coefficients in axisymmetric light sources. It is shown how this concept can be utilized for the quantitative optical investigation of axisymmetric turbulent flow.
