| PI piezo actuators and piezo motors provide very high forces and require little to no power in quasistatic applications. They can also work in a vacuum and at very low temperatures—conditions found in space applications.
PI hexapods have been used in microwave antenna alignment applications.
During the last 15 years PI has designed several large-aperture tip/tilt systems for image stabilization. Piezoelectrically-driven active secondary mirrors can improve the effective resolution up to 1000% by correcting for these image shifts in real time, especially during long integrations with weak light sources.
