人类视觉系统中的短波长颜色机制可以在空间频率上从具有相同平均辐射强度的均匀场中区分出栅格,空间频率是它可以分辨栅格中条形的最高频率的两倍。分辨率极限以上的这种辨别与类似于二维噪声的斑驳或斑驳的格栅外观有关。对斑驳图案最合理的解释是,这是一种莫尔图案,它是由不规则而稀疏的短波长圆锥体马赛克混叠(空间欠采样)产生的。
The short wavelength color mechanism in the human visual system can distinguish gratings from uniform fields of the same average radiance at spatial frequencies that are twice as high as the highest at which it can resolve bars in the grating. This discrimination above the resolution limit is associated with a splotchy or mottled appearance of the grating similar to two-dimensional noise. The most plausible explanation for the mottled pattern is that it is a moire pattern produced by aliasing (spatial undersampling) by an irregular and sparse mosaic of short wavelength cones.
