To explain the wavelength dependence of the directional sensitivity of human foveal cones (Stiles-Crawford I effect) we extended an existing fundus reflectance model for calculation of the total absorption by visual pigment. We took experimental data from literature for both the psychophysical and the optical Stiles-Crawford effect and optimized parameters to fit the experimental data. The wavelength dependence of the Stiles-Crawford effect could be well described with the geometrical optics model. Essential elements are self-screening and the inclusion of backscattered choroidal light for perception.
为了解释人眼中央凹视锥细胞方向敏感性的波长依赖性（斯泰尔斯-克劳福德I效应），我们扩展了一个现有的眼底反射率模型，用于计算视觉色素的总吸收。我们从文献中获取了心理物理学和光学斯泰尔斯-克劳福德效应的实验数据，并优化了参数以拟合实验数据。斯泰尔斯-克劳福德效应的波长依赖性可以用几何光学模型很好地描述。基本要素包括自屏蔽以及将脉络膜后向散射光纳入感知过程。
