Abstract

The invention relates to an optoelectronic access system, comprising a non-duplicatable electrically operated key (101) which emits a statically fixed light pattern (103) and comprising a spatially resolving and wavelength resolving photodetector (102) with a light output-sensitive output signal, wherein the spatial resolution of the photodetector (102) lies at least in the range of the resolution capability for the smallest wavelength of the emitted light pattern (103), said resolution capability being limited by diffraction. The invention also relates to a method for producing a non-duplicatable key (101).
