The principle of optical image stabilization is to use the stabilizing mechanism to adjust the lens or photosensitive component in the optical instrument to compensate for the light deflection of the optical instrument under the condition of external disturbance, to achieve the purpose of stable imaging, and to make the observation target image clearer. Optical image stabilization technology has a significant effect on image stabilization, so it has become a commonly used real-time optical path compensation method, has a prominent effect on reducing or eliminating external flutter, and is widely used in civilian monitoring, and camera equipment.

Unlike mechanical and electronic image stabilization, optical image stabilization technology changes the optical axis in real time to eliminate the impact of external jitter on imaging, and its driving mechanism is compact, simple to control, and hardly affected by the external environment. For high-precision, high-precision, and low-cost, optical stabilization technology is often used in high-precision equipment.

Piezo stacks and piezo actuators are linear actuators that can generate micro-nano-level displacements by utilizing the inverse piezo effect of piezo ceramics.Small size and convenient control, so it is widely used in aerospace, biomedical and precision machinery fields.

2 axis piezo nanopostioning stage is based on the principle of piezo actuators, which are connected by special hinges to form the piezo stage that can generate 2-dimensional motion, and has the advantages of piezo actuators. In addition, the control of the piezo micro-motion stage is convenient and simple, and the displacement control output of the micro-motion stage could be realized only by controlling the waveform, amplitude and frequency of the applied voltage.

The working principle of common optical image stabilization is to estimate the angle of the offset by detecting the image offset when the image is disturbed by the outside, and then the servo controller drives the piezo compensation mechanism to generate reverse motion, thereby driving the compensation movement of the compensation lens compensates the image shift caused by the disturbance, so as to achieve the purpose of stable imaging.
