摘　　要：Tomographic imaging and three-dimensional reconstruction based on a high-gain picosecond optical parametric amplifier (OPA) is demonstrated. More than 40dB intensity amplification of the image is achieved from the high-gain OPA.The images of various longitudinal positions of the target are extracted by the gated nature of the OPA,then a three-dimensional (3-D) surface topography of the target is reconstructed.The gated and high-gain property of the OPA allows tomographic optical imaging together with 3-D profile reconstruction of the target in turbid media.
