摘要

Piezoelectric actuators find their first applications in active space optics. The purpose of this paper is to describe the state of the art and some applications. Piezo actuators display attractive features for space applications, such as precise positioning, unlubricated, non-magnetic and compact features, and low power consumption. However, piezo mechanisms cannot be considered separately from their driving and control electronic. Piezo actuators, such us Amplified Piezo Actuators or Parallel Pre-stressed Actuators, initially designed under the French Space Agency contracts, shall find their first space flight applications in optics on the first European LIDAR, to be on board on AEOLUS in 2007. 1. Fine pointing of the laser beams, 2. Laser cavity tuning. Breadboard mechanisms based on piezo actuators have also been tested for refocusing purposes. Other applications includes the improvement of the CCD resolution through an over-sampling technique, such as in the SOHO/LASCO instrument, fast optical shutter operation, optical filter in combination with a Fabry - Perot interferometer, such as in future LIDAR for earth observation. The first applications shall be described and an overview of the future potential applications shall be given. The current trend is to broaden the application fields, extending them to aeronautic optic applications.
