摘要
A method and system are described for the detection and imaging of objects and structures in scattering media using light radiation. The medium is scanned with a strongly collimated light beam (2) . The light power (P.sub.b) scattered backward from the medium is detected by a receiver (17) and plotted along the scanning path. Objects (4) buried in the medium (9) are detected by the differential variation of the received light power. Information as to the size, location and depth of the objects can be obtained. The illumination by strongly collimated laser light at one or several wavelengths is preferred.
