Abstract
This invention relates to a large-scale, fully piezoelectric-driven optical tracking motion platform, belonging to the field of piezoelectric drive technology. It solves the problem that traditional electromagnetic actuators require complex mechanisms and large dimensions to achieve high resolution, high load, and a large working range. Simultaneously, it offers advantages such as fast response, high resolution, power-off self-locking, and no electromagnetic interference. The optical tracking motion platform includes a base, a horizontal axis rotary actuator, an upper worktable, an imaging system, a lower worktable, a Z-axis rotary actuator, a reflection adjustment system, and a control system. By combining different timing signals to different piezoelectric actuators, accurate reception of signals from any optical path can be achieved, with a large working angle. Furthermore, the system possesses high precision and sensitivity.
