The piezo tip/tilt mirror is designed based on a single piezoelectric ceramic structure,
using piezoelectric ceramic, deflecting movement in a push-pull mode stroke, and using
a bridge connection circuit control, which could eliminate the influence of temperature
on the piezoelectric ceramic, under a wide range of temperature changes Maintain good
angular stability.
