摘　　要：以宽带连续光为光源对隐藏在强散射随机介质中的吸收物体成像进行了实验研究，用一种新的图像处理方法恢复了被散射光所淹没的吸收物体的像。由于人体组织为光的强散射介质，因此该研究在医学成像中有很大的潜在应用价值。Imaging of an absorbing object hidden in highly scattering random media is achieved with a CW broadband light from a luminous diode. A new image processing algorithm is developed to restore the image covered by the diffuse light. Submilimeter spatial resolution is achieved. This method may find the important potential application in medical imaging.
