MARKING SYSTEM WITH CHIRAL ARRANGEMENT

摘要

The invention provides a marking system for transparent objects comprising at least one arrangement of markers which arrangement comprises at least one marker, wherein the arrangement is a chiral arrangement adapted to provide a chiral function, with chiral function meaning that the chiral arrangement is adapted to provide orientation with regard to inversion, rotation and translation of, transparent, inversionally asymmetric objects. The invention also provides a transparent object comprising at least one marker to provide orientation with regard to inversion, rotation and translation of the objects in relation to a reference position, wherein the marker has a chiral structure adapted to provide a chiral function. Unambiguous positioning is relevant for objects with rotational asymmetry, inversional asymmetry and objects with a combination of rotational asymmetry and inversional asymmetry. In the latter case, the anterior and posterior surfaces of a transparent object have different functions and should be positioned accordingly.
