Abstract

Echo broadening effect (EBE) is inherent in three-dimensional range-gated imaging (3DRGI). The effect impacts the range-intensity profile of gate images which is crucial in three approaches of 3DRGI based on depth scanning, supperresolution depth mapping and gain modulation. In this paper, we give the space-time model of EBE which illustrates three typical range-intensity profiles under different temporal parameters of laser pulse and gate pulse. A head zone and a tail zone exist in both sides of the profiles. Our research demonstrates that EBE should be suppressed in depth scanning and gain modulation methods and utilized in supperresolution depth mapping.
