：描述了测量三个受试者的视网膜反射率作为波长函数的实验。研究了反射光的两个成分：保持偏振的成分和去偏振的成分。发现这两种成分都存在于所有可见波长处，并且其幅度在光谱的红端上升，尽管保留偏振的反射光的比例较低。结果与早期研究的结果进行了比较。虽然视网膜反射率的波长依赖性的形式存在定性一致，但不同作者推导出的值的大小差异很大。讨论了眼双折射对视网膜偏振光研究的影响，以及负责观察到的反射率的结构的可能位置。
: Experiments are described in which retinal reflectance was measured as a function of wavelength for three subjects. Two components of the reflected light were studied: that which retained polarization and that which was depolarized. Both components were found to be present at all visible wavelengths and to have magnitudes which rose at the red end of the spectrum, although the fraction of the reflected light which retained polarization was then lower. The results are compared with those of earlier studies. While there is qualitative agreement on the form of the wavelength-dependence of retinal reflectance, the magnitudes of the values deduced by different authors vary considerably. The influence of ocular birefringence on polarized-light studies of the retina is discussed, together with possible locations from the structures responsible for the observed reflectances.
