Fibre optic gyrometer non reciprocal measurement mechanism having light source and optical monomode filter with polarization separator producing light paths and polarization state detector.

摘要

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.
