Paper Abstract

In the present publication we investigate 3D range-gated imaging in scattering environments. Experimental data was obtained from measurements in a fog chamber as well as in the Baltic Sea using an underwater range-gated imaging system. A detailed analysis of this data reveals that the reconstruction of 3D information is disturbed by the impact of scattering environments. As a result a first model was set up for the propagation of light in the range-gated imaging process. This model is the basis for the development of image post-processing algorithms applying least-square curve-fitting methods. A pixel-wise least square curve-fitting of experimental data reveals the contribution of diffuse scattered light from neighboring areas on the imaging process. Therefore, an extended spatial-temporal model which took into account the diffuse scattered light was set-up and discussed.
