摘要 测量了偶氮染料甲基红掺杂PMM A薄膜的反射光谱,并对测量结果进行了修正.利用修正后的反射光谱进行了k-k变换,获得了样品的折射率分布.对样品进行了不同状态下吸收光谱的测量,利用k-k变换获得了样品在不同状态下折射率的变化分布. The reflection spectrum of Methyl Red doped PMMA was measured and modified. The refractive index of sample was gained by calculation of Kramers-Kronig relation with the data of the reflection spectrum. The absorption spectrums of trans and cis states were measured separately. The refractive index change of the sample is gained with the data.
