摘要： To effectively reduce a measurement error in a parameter indicating two-dimensional spatial distribution of a state of polarization generated by variations in retardation of a birefringent prism pair due to a temperature change or other factors, while holding a variety of properties of an imaging polarimetry using the birefringent prism pair. By noting that reference phase functions φ1(x, y) and φ2(x, y) are obtained by solving an equation from each vibration component contained in an intensity distribution I(x, y), the reference phase functions φ1(x, y) and φ2(x, y) are calibrated concurrently with measurement of two-dimensional spatial distribution S0(x, y), S1(x, y), S2(x, y), and S3(x, y) of Stokes parameters.

摘要： A measuring apparatus includes a light intensity information acquisition section 40 that acquires light intensity information relating to a measurement light containing a given band component, the measurement light having been modulated by optical elements included in an optical system 10 and a measurement target (or a sample 100), and a calculation section 50 that calculates at least one matrix element of a Mueller matrix that indicates the optical characteristics of the measurement target based on the light intensity information relating to the measurement light and a theoretical expression for the light intensity of the measurement light. The light intensity information acquisition section 40 acquires the light intensity information relating to a plurality of the measurement lights obtained from the optical system 10 by changing setting of a principal axis direction of at least one of the optical elements. The calculation section 50 performs a carrier amplitude coefficient calculation process, and a matrix element calculation process that calculates the at least one matrix element based on a carrier amplitude coefficient and the theoretical expression for the carrier amplitude coefficient including the at least one matrix element.

摘要： In the channeled spectroscopic polarimetry, a measurement error of a parameter showing a spectropolarization characteristic of a sample is effectively removed, the error being generated by various variations in retardation of a retarder depending upon the state of the sample. With attention being focused that the retardation of the retarder may be kept constant by stabilization of an incident direction of light that transmits through the retarder, the retarder was arranged on the light source side with respect to the sample so as to effectively remove an influence relative to a measurement error, such as variations in direction of a light ray due to the sample.
