In camera or other similar imaging equipment, the sharpness of image is critical. The gyroscope in the camera detects the slight movement and transmits the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated, and then through the compensation group, it is compensated according to the camera shake direction and displacement, and the position is adjusted accordingly. So as to effectively overcome the image blur caused by camera vibration.
Piezoelectric actuators are widely used in camera anti-shake technology as micro-displacement compensation electronic components. Piezoelectric actuators using stack co-firing process have excellent performance and long service life, and are suitable for variety of scientific experiments and industrial applications. At the same time, PZT have the advantages of high resolution, small size, easy integration, large output force and fast response speed, and they play key role in many high-precision applications.
