POLARIZATION PROPERTY MEASUREMENT METHOD AND POLARIZATION PROPERTY MEASUREMENT DEVICE

摘要

To provide a polarization property measurement method capable of reducing a sampling number to reduce load on arithmetic processing, and accurately measuring polarization properties.SOLUTION: A polarization property measurement method comprises: a first process of making light incident into a detector 15 in a first state where between a polarization modulation unit 12 into which light is made incident from a light source 11, and a polarization analysis unit 14 configured to emit light to the detector 15, a sample 13 is not installed, and causing calculation means 16 to use an output signal from the detector 15 at a current time to obtain a first Stokes vector indicating the first state; a second process of making light incident into the detector 15 in a second state where between the polarization modulation unit 12 and the polarization analysis unit 14, the sample 13 is installed, and obtaining a second Stokes vector indicating the second state, using an output signal from the detector 15 at a current time; and a third process of obtaining a Mueller matrix indicating polarization properties of the sample 13, using a matrix indicating the first Stokes vector and a matrix indicating the second Stokes vector.SELECTED DRAWING: Figure 1
