Abstract

In order to suppress the influence of accidental reflections on a target which is marked with reflectors in the case of illumination with polarised radiation, the two reflection components are separated by use of a polarisation-selective element in the beam path. The method thus modifies the desired reflection in a deliberate manner, while leaving the undesired reflection uninfluenced. <IMAGE>
