Abstract (en)
[origin: FR2824906A1] The non reciprocal measurement mechanism has a source of light (1) , an optical monomode filter (52) and two paths (81,82) from a light separator (7). The separator is a polarization separator, the filter is non polarizing. The detector (3) has a system of analysis of the polarization state.
