Novel technologies for large deformable mirrors
Mel Strachan,David James Montgomery,Richard M. Myers,Kevin Cooke,Joanne Hampshire,Matthias Kroedel,J. H. Hough,Sheila Rowan,Marielle van Veggel,Katherine J. Kirk,Erman Uzgur,Shin-Sung Kim,Martin Strangwood +12 more
TL;DR: In this paper, a deformable mirror surface material, a compliant from of silicon carbide, offers a Young's Modulus comparable to glass but with greater, non-catastrophic, resistance to fracture.

Extension sensing of piezo actuators using time-domain ultrasonic measurement and frequency-domain impedance measurement
TL;DR: In this article, three different techniques of extension sensing for multilayer piezoelectric actuators, to provide a suitable method which involves primarily overcoming the inherent hysteretic behaviour of PAs materials.

Multilayer Ultrabroadband Piezocomposite Transducer: Fabrication and Characterization
TL;DR: In this paper, a dual-layer piezocomposite transducer was designed by combining two 1-3 transducers with various thicknesses to couple their resonance frequencies and to increase the bandwidth.

Overcoming hysteresis in multilayered piezoceramic actuators used in adaptive optics.
Emma Bryce,Erman Uzgur,David Hutson,Katherine J. Kirk,Mel Strachan,Noah Schwartz,Phil Parr-Burman +6 more
TL;DR: In this article, two methods to overcome the inherent, non linear hysteresis that is present in multilayered piezoceramic actuators are discussed. But they often involve complex additions to the actuators and its positioning system.
