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.

Device for localizing an object in a turbid medium

A shaving apparatus comprises a housing provided with a first shaving member having a first cutting edge and with a second shaving member having a second cutting edge, which second shaving member is drivable relative to the first shaving member, the movement of the second cutting edge relative to the first cutting edge in a plane transverse to the cutting edges being composed of the movements in two main directions in this plane. The second shaving member is provided with a carrier mounted in the housing so as to be movable in both main directions and the carrier comprises two surfaces which extend transversely of the main directions and which engage against a rotatably drivable cam disc.
