Piezo tip/tilt systems from PI (Physik Instrumente) are versatile positioning systems ─ they are ideal for dynamic operation in applications such as scanning, tracking, for suppressing drift oscillation or dynamic image stabilizing. Piezo tip/tilt systems and scanners offer greater acceleration and dynamic bandwidth than similar actuators such as for example, voice coil or galvanometer scanners. Piezo tip/tilt systems developed by PI are also found in applications for quasistatic positioning of optics with high demands on "pointing stability".
The new white paper offers a sound insight into the basics of piezo tip/tilt systems. The design and functional principle are explained as well as the delivery condition and system quality. The paper also provides important information on handling mirrors and how piezo tip/tilt systems are controlled and operated. Supplemental information is also provided and includes application examples from OEM engineering, and FEM optimization. Here is a short overview of the questions dealt with in the white paper:
