Abstract:
1. A method of analysing an input signal, the method including the steps of: (a) dividing a first input signal into first and second orthogonal signal polarization components; (b) dividing a second input signal into first and second orthogonal local polarization components; (c) mixing the first signal polarization component with the second local polarisation component to provide a resultant first mixed polarization component, wherein the first signal polarization component is orthogonal to the second local polarization component; (d) mixing the second signal polarization component with the first local polarisation component to provide a resultant second mixed polarization component, wherein the second signal polarization component is orthogonal to the first local polarization component; and (e) analysing the polarization state of the first and second mixed polarization components to determine the polarization or phase information in the input signal.
