Abstract

A correlator-optical imaging system with three-dimensional nano- and micro-structured diffraction gratings in aperture and in image space allows an adaptive optical correlation of local RGB data in image space with global RGB data (light from overall illumination in the visual field scattered from the aperture of the optical imaging system into image space), diffracted together into reciprocal grating space (photoreceptor space). This correlator-optical hardware seems to be a decisive part of the human eye and leads to new interpretations of color vision and of adaptive color constancy performances in human vision. In Part I, the up to now available data and their corresponding interpretation, together explaining paradoxically colored shadows as well as the data from E.Land's Retinex experiments, will be described. They will serve as premises for the planned experimental setup. In Part II these premises will experimentally be controlled by experiments in a part of an actually starting R+D project and the results will be described in 2007.
