A sensor system includes a sensor head, an optical source, and a measurement apparatus. The sensor head includes a beamsplitter having first, second, third, and fourth ports, the beamsplitter being responsible to light selectively applied to the first, second and third ports for passing light of a first polarization state from the first port to the second port, for passing light of a second polarization state, from the first port to the third port, for passing light of the second polarization state from the second port to the fourth port, and for passing light of the first polarization state from the third port to the fourth port. The optical source means provides light to the first port. The sensor head further includes a bidirectional polarimetric sensor responsive to polarized light output by the beamsplitter at the second and third ports and to an electromagnetic field applied to the polarimetric sensor for producing first polarized light at said third port and for producing second polarized light at said second port.
