Aberration Corrected TEM and Exit Wave Reconstruction
In this workshop we will discuss TEM image formation under aberration corrected conditions
and the process of exit wave reconstruction.
The workshop will initially examine the essential electron optics relevant to hexapole
aberration correctors used in TEM. Subsequently, the wave aberration function will
be introduced together with experimental methods available for the measurement of
individual aberration coefficients.
Subsequently, the basic principles of exit wave restoration will be examined and
a practical demonstration using the FTSR software available from HREM research will
