Abstract
A device (700) for localizing an object (726) in a turbid medium (710) includes one light source (722) and two detectors (723,724), being symmetrically situated relatively to the light source (722), around a turbid medium (710). By applying a pulse modulated light source an optimal frequency could be determined to perform measurement at optimal sensitivity of the system. To enable a fast scanning system that could be used in for example mammography, a plurality of light sources (1209) and plurality of detectors (1201 to 1208) could be used. A processing system (105) selects then repetitively one light source (1209) and a different detector pairs, that are symmetrically situated relatively towards the light source (1209). Another embodiment that could be used in the mammography includes rotating mirrors (1303,1309) to scan a measuring space (1304) adapted to contains an object (1305), for example a human breast. The detector used in this embodiment includes a streak camera (1313). A lens (1308) and one of the rotating mirrors (1309) images two exit locations (1306,1307) of the measuring space (1304) that are symmetrically situated toward an entrance location (1303) of the measuring space on the entrance slit (1312) of the streak camera (1313). The output-image (1315) of the streak camera (1313) is imaged by an image pick-up device (1316) and processed by a processing system (1318) to obtain an image of the object in the measuring space (1304). A monitor (1319) displays the obtained image.
