| Modern HiTechnologies often use physical effect, which are
extremely sensitive in magnitude to any small deviation from the correct position of the
mechanical components of the device. Any misalignment e.g. by thermal drifts can diminish
the device performance e.g. the optical output power of a discretely setup laser
resonator. Other example are the coupling efficiency of freely coupled optical fibers,
interferometers, sensor/transducer arrangements in microsystems, biological systems, etc. To ensure a stable optimum operation the task is to detect the onset of mechanical misalignment and to readjust the components actively. For micor- and nanopositioning purposes, the first choice include all kinds of Piezoelectric actuated systems such as stacks, bimorphs, hybrid systems etc. The stabilization electronics PiStab-2 controls up to 2 degrees of freedom for mechanical longterm stabilization of position sensitive effects.
