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.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
