ABSTRACT:
The systems and methods described herein are directed to motion transformers as well as their integration and/or assembly, for use in directing optical beams and positioning of small optical elements for creating a variety of tunable optical components. More particularly, the systems and methods can be applied to a free-space optical cross-connect switching apparatus with piezoelectric actuation.
