In three-dimensional (3-D) fluorescence images produced by a confocal scanning laser microscope (CSLM), the contribution of the deeper layers is attenuated due to absorption and scattering of both the excitation and the fluorescence light. Because of these effects a quantitative analysis of the images is not always possible without restoration. Both scattering and absorption are governed by an exponential decay law. Using only one (space-dependent) extinction coefficient, the total attenuation process can be described. Given the extinction coefficient we calculate within a non-uniform object the relative intensity of the excitation light at its deeper layers. We also give a method to estimate the extinction coefficients which are required to restore 3-D images. An implementation of such a restoration filter is discussed and an example of a successful restoration is given. |
