摘要
利用干涉仪，用连续激光作光源实现了对隐藏在强散射介质中吸收物体的成像，并采用了一种新的滤波算法──阈值密度滤波器，处理干涉条纹中的散斑噪声，达到了亚毫米级的空间分辨率．
In this paper an absorbing object hidden in a highly scattering medium is shown to be visibleunder the illumination of a cw coherent light by using interferometry,and a new filtering algorithm thethreshold density filter is used to extract interference pattern from the speckle noise background fast andefficiently. The submillimeter spatial resolution is achieved.
