    Abstract: A grating optical sensor includes: a lens imaging an object space; a diffractive hexagonal 3D grating optical modulator in the image plane of the lens to form at least one trichromatic RGB diffraction pattern; a photoelectric receiver arrangement arranged in the near field downstream of the modulator, having individual receivers configured to generate electric signals in accordance with centrosymmetrically trichromatic RGB diffraction orders of the diffraction pattern; an evaluation device for the electric signals generated by the individual receivers; and at least one light-diffusion plate arranged in either a pupillary plane of the lens or a papillary plane conjugate to the lens or both.
