Paper Abstract

In the present paper 3D range-gated imaging in scattering environments is investigated. 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 ICCD camera. Both, laser pulse width and exposure time were in the range of 500 ps. To evaluate the impact of scattering environment on the depth resolution capability of the imaging system the Lissajous eye pattern analysis was applied. This analysis gives experimental evidence of the reduction of depth accuracy in the presence of scattering media in the imaging range. Further, 3D information was reconstructed from tomography data using the least-square-fitting method. This 3D reconstruction verifies the results of the Lissajous eye pattern analysis.
