    Laser interferometry seems to be a solution not only due to its direct traceability to the fundamental etalon of length but also the incremental interferometer in its fringe counting mode gives an excellent dynamic range limited only by the fluctuations of the refractive index of air and offers nanometer or even subnanometer resolution over large range. We concentrated onto a small range flexture three-axis nanopositioning stage equipped with closed-loop motion control with capacitive sensors embedded in a frame with six-axes interferometric system supplied from a stabilized single-frequency frequency doubled 532 nm Nd:YAG laser.
