Abstract
An optical measuring process for determining a longitudinal position of a set of re-emitting sources on a sample includes: (i) projecting an excitation light distribution onto the sample so as to cause the set of sources on the sample to re-emit light in a dark helix light pattern having two nulls spatially separated by a boundary an axis connecting the two nulls; and (ii) determining the longitudinal position of the set of re-emitting sources by measuring an angular position of the axis.
