Abstract
The light to be generated by a light source in a device for localizing an object in a turbid medium is successively coupled into the turbid medium from different directions by use of an optical detection unit. The light coupled in is transported in different directions through the turbid medium. A part of the light emanating from the turbid medium is measured by use of photodetectors. An image of the interior of the turbid medium is reconstructed by optical tomography on the basis of the measured intensities. The device includes structure which reduces variations in the intensity of the light coupled into the turbid medium from the same direction in order to reduce errors occurring on repeated executions of the measurements for successively localizing the object.
