Mueller matrices for normal transmission of light through a birefringent slab are formulated to analyze retardation and depolarization. A finite wave band, wedge slab, and microroughness may cause a spread in retardance, which in turn produces depolarization. The spectra of depolarization, cross-polarized transmittance, and retardance by rotating-analyzer ellipsometry are simulated for the quasi-monochromatic effect with a finite bandwidth. These spectra agree excellently with the measured spectra for a sapphire slab. The depolarization spectrum simulated for the wedge effect fits the measured spectrum in the long-wave region but is too small in the short-wave region. The depolarization simulated for incoherent multiple reflections demonstrates the oscillating structure, which is small compared with the measured depolarization. The finite bandwidth effect contributes more than the other effects to the measured depolarization of a sapphire slab.
用于分析光通过双折射平板的正常传输的穆勒矩阵被公式化以分析相位延迟和去极化。有限的波段、楔形平板和微粗糙度可能会导致相位延迟的展宽，这反过来又会产生去极化。通过旋转分析器椭圆偏振法模拟了有限带宽的准单色效应下的去极化光谱、交叉偏振透射率和相位延迟光谱。这些光谱与蓝宝石平板的测量光谱非常吻合。针对楔形效应模拟的去极化光谱在长波区域与测量光谱相符，但在短波区域太小。针对非相干多次反射模拟的去极化显示出振荡结构，与测量的去极化相比很小。有限带宽效应比其他效应对蓝宝石平板测量的去极化贡献更大。
