Abstract:
This invention relates to a beam steering mechanism with ultrahigh frequency response and high sensitivity, which is based on the translation of two mirrors. Beam steering is achieved by the translations of two mirrors in the X axial mirror group and Y axial mirror group. The two translation mirrors are located at the output ends of two PZT actuators, and are directly actuated by the two PZT actuators. The dynamic characteristics of the two translation mirrors are always exactly the same as the output characteristics of the PZT actuators. There is no mechanical translation loss in this beam steering mechanism, and so, the beam steering mechanism has an ultrahigh frequency response and high angular deflection sensitivity.
