An imaging polarimeter using liquid-crystal variable retarders (Bueno, J. M., Artal, P. (1999). Double-pass imaging polarimetry in the human eye. Optics Letters, 24, 64-66) has been used to study the parameters of polarization in the living human eye. Retardation introduced by birefringent structures of the eye has been calculated by using a spatially resolved collection of Mueller matrices obtained from series of 16 double-pass retinal images. Results for images with a 2-mm pupil diameter show that although the retardation introduced by the eye in a double-pass varies among individuals, at the central cornea the slow axis is directed along the upper-temporal to lower-nasal line and the ellipticity is close to zero, which indicates the presence of linear birefringence. As pupil size increased, the measured retardation also increased, while ocular birefringence remained linear and azimuthal angle changed without a clear tendency.
一种使用液晶可变延迟器的成像偏振计（布埃诺，J.M.，阿塔尔，P.（1999年）。人眼的双程成像偏振测量法。《光学快报》，24，64 - 66）已被用于研究活体人眼的偏振参数。通过使用从一系列16张双程视网膜图像获得的穆勒矩阵的空间分辨集合，计算出了眼睛双折射结构引入的延迟。2毫米瞳孔直径图像的结果表明，尽管眼睛在双程中引入的延迟因人而异，但在中央角膜处，慢轴沿颞上至鼻下线方向，椭圆率接近零，这表明存在线性双折射。随着瞳孔尺寸增大，测量到的延迟也增加，而眼双折射保持线性，方位角变化无明显趋势。
