Title:
分光偏光計測方法
Document Type and Number:
Japanese Patent JP4224644
Kind Code:
B2
Abstract:
To effectively reduce a measurement error in a parameter indicating a state of spectroscopic polarization generated by variations in retardation of a retarder (R 1 , R 2 ) 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 Æ 1 (Ã) and Æ 2 (Ã) are obtained by solving an equation from each vibration component contained in a channeled spectrum P(Ã), the reference phase functions Æ 1 (Ã) and Æ 2 (Ã) are calibrated concurrently with measurement of spectrometric Stokes parameters S 0 (Ã), S 1 (Ã), S 2 (Ã) , and S 3 (Ã).
