1. A method for imaging a three-dimensional target object or other optical inhomogeneity in a turbid medium, comprising the steps of:

  • providing a substantially collimated beam of radiation and directing the beam onto a surface of a turbid medium containing a target object;

    providing a substantially collimated receiver to receive scattered radiation;

    performing positional scans comprising source-detector configurations having different source detector, separations and angles of the scattered radiation over the surface of the turbid medium at various separations and angles;

    applying the data obtained from each positional scan to form a three-dimensional image of the target object by;

    a. determining attenuation of emerging radiation from said target medium relative to a model medium;

    b. determining a relative contribution of volume elements for each source-detector configuration;

    c. superimposing the relative contribution of volume elements for all source-detector configurations;

    d. obtaining a spectroscopic image;

    e. displaying said spectroscopic image.
