Paper Abstract

We investigate range-gated imaging in scattering environments. Experiments were carried out in a fog chamber with different fog densities using a range-gated imaging system based on 532-nm laser illumination and an intensified charge-coupled device camera. The laser pulse width and the sensor exposure time were in the range of 500 ps. For the analysis of the impact of scattering environment on the depth resolution capability of the imaging systems, the Lissajous eye pattern method was applied. These analyses gave experimental evidence of the reduction of depth accuracy in the presence of scattering media. Further, the experimental data were compared to three-dimensional reconstruction using the least-square curve-fitting method.
