Polarization state measuring apparatus, circular dichroism measuring apparatus, and its method

摘要: PROBLEM TO BE SOLVED: To provide a compact and inexpensive polarization state measuring apparatus with improved measurement precision time, to circular dichroism apparatus. SOLUTION: The (10) comprises first polarizer (22) for transmitting prescribed polarized component of light including band component; modulation means (24) modulating transmitted through the into desired light; second (48) an object be measured (S) via means; detection (50) detecting optical intensity polarizer; (52) measured, on basis Fourier coefficients, when detected by is expressed in series. liquid crystal elements (26 28) voltage control (30 32) controlling applied elements.
