Diffraction of light at the spatial cellular phase grating outer nuclear layer of the retina could produce Fresnel near-field interferences in three RGB diffraction orders accessible to photoreceptors (cones/rods). At perpendicular light incidence the wavelengths of the RGB diffraction orders in photopic vision-a fundamental R-wave with two G+B-harmonics-correspond to the peak wavelengths of the spectral brightness sensitivity curves of the cones at 559 nmR, 537 nmG, and 447 nmB. In scotopic vision the R+G diffraction orders optically fuse at 512 nm, the peak value of the rod's spectral brightness sensitivity curve. The diffractive-optical transmission system with sender (resonator), space waves, and receiver antennae converts the spectral light components involved in imaging into RGB space. The colors seen at objects are diffractive-optical products in the eye, as the German philosopher A. Schopenhauer predicted. They are second related to the overall illumination in object space. The RGB transmission system is the missing link optically managing the spectral tuning of the RGB photopigments.
光在视网膜的空间细胞相位光栅外核层发生衍射，可能会在光感受器（视锥细胞/视杆细胞）可及的三个RGB衍射级次中产生菲涅耳近场干涉。在垂直光入射时，明视觉中RGB衍射级次的波长——一个基本的R波和两个G + B谐波——分别对应视锥细胞光谱亮度灵敏度曲线的峰值波长，即559nmR、537nmG和447nmB。在暗视觉中，R + G衍射级次在512nm处发生光学融合，这是视杆细胞光谱亮度灵敏度曲线的峰值。具有发射器（谐振器）、空间波和接收器天线的衍射光学传输系统将成像过程中涉及的光谱光成分转换为RGB空间。正如德国哲学家A.叔本华所预言的，物体上看到的颜色是眼睛中的衍射光学产物。它们与物体空间中的整体照明存在二次关联。RGB传输系统是在光学上管理RGB光色素光谱调谐的缺失环节。
