We developed a simple mounting scheme for piezoelectric actuators to precisely control mirror displacement up to high frequencies. This method ensures uniform response and no phase lag, ideal for optical applications.

Area of Science:

  • Optics and Photonics
  • Mechanical Engineering
  • Materials Science

Background:

  • Piezoelectric actuators are crucial for precise motion control in optical systems.
  • Existing mounting methods can introduce limitations like phase lag and limited frequency response.
  • Controlling displacement of mirrors and small objects requires stable, high-frequency actuation.

Purpose of the Study:

  • To propose and demonstrate a novel mounting scheme for cylindrical piezoelectric actuators.
  • To achieve uniform displacement response and eliminate phase lag up to high frequencies.
  • To enable compact and cost-effective piezoelectric mirror control systems.

Main Methods:

  • A simple ring holder design was employed, utilizing unmodified off-the-shelf components.

  • The piezoelectric actuator-mirror assembly was side-clamped at its zero-displacement plane.
  • This decoupling strategy targets the fundamental elongation mode to minimize holder influence.

    • Main Results:

    • The proposed mounting scheme achieved a uniform response with no phase lag up to high frequencies.
    • The first mechanical resonance of the piezo-mirror assembly was observed around 120 kHz.
    • A reduction in mirror displacement by a factor of 2 was noted, with achieved displacement of ~2.5 μm.

    Conclusions:

    • The novel mounting scheme effectively controls mirror displacement using piezoelectric actuators.
    • The system offers a compact solution suitable for integration into standard optical mounts.
    • This approach provides a stable, high-frequency actuation method for optical components.
