ABSTRACT:
To effectively reduce a measurement error in a parameter indicating a state of spectroscopic polarization generated by variations in retardation of a retarder due to a temperature change or other factors, while holding a variety of properties of a channeled spectroscopic polarimeter. By noting that reference phase functions φ1(σ) and φ2(σ) are obtained by solving an equation from each vibration component contained in a channeled spectrum P(σ), the reference phase functions φ1(σ) and φ2(σ) are calibrated concurrently with measurement of spectrometric Stokes parameters S0(σ), S1(σ), S2(σ), and S3(σ).
