4D-RGB diffractive-optical correlator in the human eye: the hardware for a hierarchy of spectral space-time transformations in color vision

3D space and time in optics and in human vision are linked together in spectral diffractive-optical transformations of the visible world. A 4D-RGB correlator hardware - integrated in an optical imaging system like the human eye - processes a hierarchy of relativistic equilibrium states and a sequence of double-cone transformations. The full chain of light-like events ends in von Laue interference maxima in reciprocal space, where 4D-RGB signals are miniaturized down to the level of individual photoreceptors. The diffractive-optical correlator relates local information to global data in the visual field and illustrates the potential of future development of cameras towards more intelligent 4D optical sensors.
