The invention relates to an identification method carried out as follows. A surface structure and an inner structure of a body member are measured (ST-ST, ST) so as to obtain a surface-structure measurement result (FPM) and an inner-structure measurement result (BVPM), respectively. The surface-structure measurement result (FPM) is compared (ST) with a surface-structure reference result (FPR) that distinguishes an individual from other individuals. The inner-structure measurement result (BVPM) is compared (ST) with an inner-structure reference result (BVPR) that is associated with the same individual and that distinguishes the individual from other individuals. The body member may be, for example, a finger. In that case, the surface structure comprises a fingerprint and the inner structure comprises a blood-vessel pattern.

Lithographic alignment system and device manufacturing method

The invention describes a method of determining the position of fluorescent markers in a sample (), with a high spatial resolution. To this end, the sample () is illuminated with an exciting light beam (), while the sample () is simultaneously scanned by a particle beam (). During scanning, markers will be impinged upon by the particle beam () and will be damaged, in such a manner that the marker impinged upon will no longer emit fluorescence radiation. This leads to a reduction of the flux of fluorescence radiation. This reduction is detected. Seeing as the position of the particle beam () w.r.t. the sample is known at the moment that the marker is damaged, the position of the marker in the sample is, accordingly, also known.
