**FOR FURTHER INFORMATION CONTACT:**
Ms. Joan Gilsdorf, Patent Attorney, e-mail: *[email protected]* (256) 955-3213 or Ms. Susan D. McRae, Office of Research and Technology Applications, e-mail: *[email protected];* (256) 955-1501.
**SUPPLEMENTARY INFORMATION:**
The invention pertains to determining the state of polarization of an electromagnetic signal. A polarimeter includes a receiver that receives a first polarization (P1) of the signal and splits the first polarization of the signal into the in-phase (I <sub>P1</sub> ) and quadrature (Q <sub>P1</sub> ) components, and receives a second poplarization (P2) of the signal and splits the second polarization of the signal into the in-phase (I <sub>P1</sub> ) and quadrature (Q <sub>P2</sub> ) components. The polarimeter may also include a processor that receives each of the in-phase and quadrature components ((I <sub>P1</sub> ), (Q <sub>P1</sub> ), (I <sub>P2</sub> ), and (Q <sub>P2</sub> )) of the first and second polarizations and determines the Stokes polarization vector components (s <sub>0</sub> , s <sub>1</sub> , s <sub>2</sub> , and s <sub>3</sub> ) of the signal.
