A novel method for analyzing optical characteristics of an optical medium is disclosed. The method comprises illuminating an optical medium, having an input surface and an output surface of light, with at least three input light beams differed from each other in a polarization state, respectively from a direction inclined by a polar angle theta (0°<theta<90°) with regard to the input surface; obtaining polarization states of output light beams coming out from the output surface, corresponded to the input light beams; and determining the Jones matrix M which can satisfy the equation (1) below with polarization vectors of the input light beams and polarization vectors of the output light beams: <maths id="MATH-US-00001" num="1"> <MATH OVERFLOW="SCROLL"> <MTABLE> <MTR> <MTD> <MROW> <MROW> <MO>(</MO> <MTABLE> <MTR> <MTD> <MSUP> <MI>Es</MI> <MI>'</MI> </MSUP> </MTD> </MTR> <MTR> <MTD> <MSUP> <MI>Ep</MI> <MI>'</MI> </MSUP> </MTD> </MTR> </MTABLE> <MO>)</MO> </MROW> <MO>=</MO> <MROW> <MSUP> <MI>Q</MI> <MI>'</MI> </MSUP> <MO>x</MO> <MI>M</MI> <MO>x</MO> <MI>Q</MI> <MO>x</MO> <MROW> <MO>(</MO> <MTABLE> <MTR> <MTD> <MI>Es</MI> </MTD> </MTR> <MTR> <MTD> <MI>Ep</MI> </MTD> </MTR> </MTABLE> <MO>)</MO> </MROW> </MROW> </MROW> </MTD> <MTD> <MROW> <MO>(</MO> <MN>1</MN> <MO>)</MO> </MROW> </MTD> </MTR> </MTABLE> </MATH> </MATHS> where, Es and Ep are polarization vectors of s-polarization and p-polarization of an input light beam, respectively; Es' and Ep' are polarization vectors of s-polarization and p-polarization of a correspondent output light beam, respectively; Q is a dynamics matrix expressing change in a polarization state of an input light beam going into the optical medium from the air; and Q' is a dynamics matrix expressing change in a polarization state of an output light beam going out the optical medium into the air.
