Claim 0:
1. An apparatus for observing a sample, comprising:
a deflector configured to form a plurality of deflected charged-particle beams from a primary charged-particle beam comprising a plurality of pulses of charged particles and deflect the plurality of pulses of charged particles to a plurality of probe spots on a sample;
a detector configured to detect a plurality of signals from the sample that result from the plurality of pulses interacting with the sample; and
a controller configured to correlate a particular detected signal to a particular probe spot on the sample based on a correlation between a time that the particular signal generated from the particular probe spot was detected and a time associated with a time that a particular charged particle pulse forming the particular probe spot was deflected.
