This study investigated the measurement of circular dichroism (CD) spectra without controlling a phase modulator. In a conventional CD system, the peak retardation of the phase modulator must remain constant over the observed wavelength range. Thus, the phase modulator must be controlled to maintain an appropriate modulation degree at an observed wavelength. In contrast, CD obtained using retardation domain analysis is not affected by peak retardation. Consequently, CD spectra can be measured without control of the phase modulator, which was experimentally demonstrated in this study. Additionally, linear dichroism spectra were obtained using retardation domain analysis.
本研究探讨了在不控制相位调制器的情况下测量圆二色性 (CD) 光谱的方法。在传统的 CD 系统中,相位调制器的峰值延迟必须在观测波长范围内保持恒定。因此,必须控制相位调制器以在观测波长处保持适当的调制程度。相比之下,使用延迟域分析获得的 CD 不受峰值延迟的影响。因此,可以在不控制相位调制器的情况下测量 CD 光谱,本研究对此进行了实验验证。此外,还使用延迟域分析获得了线二色性光谱。
