Journal ArticleDOI
Open-loop control of a MEMS deformable mirror for large-amplitude wavefront control
TL;DR: In this paper, a method for predicting control voltages that will generate a prescribed surface shape on a MEMS deformable mirror was proposed based on an analytical elastic model of the mirror membrane and an empirical electromechanical model of its actuators.
Journal ArticleDOI
Polymer microcantilevers fabricated via multiphoton absorption polymerization
Zeynel Bayindir,Y. Sun,Michael J. Naughton,Christopher N. LaFratta,Tommaso Baldacchini,John T. Fourkas,Jason B. Stewart,Bahaa E. A. Saleh,Malvin C. Teich +8 more
TL;DR: In this article, the authors used multiphoton absorption polymerization to fabricate a series of micro-scale polymer cantilevers and extracted a Young's modulus of E=0.44GPa.
Journal ArticleDOI
Design and development of a 331-segment tip–tilt–piston mirror array for space-based adaptive optics
Jason B. Stewart,Thomas G. Bifano,Thomas G. Bifano,Steven Cornelissen,Paul Bierden,B. Martin Levine,Timothy A. Cook +6 more
TL;DR: In this article, a micromachined silicon deformable mirror (DM) system for the hyper-contrast visible nulling coronagraph architecture designed by the Jet Propulsion Laboratory for NASA's Terrestrial Planet Finding (TPF) mission is presented.
Proceedings ArticleDOI
MEMS deformable mirrors for astronomical adaptive optics
Steven Cornelissen,Allyson L. Hartzell,Jason B. Stewart,Thomas G. Bifano,Thomas G. Bifano,Paul Bierden +5 more
TL;DR: In this paper, the authors report on the development of high actuator count, micro-electromechanical (MEMS) deformable mirrors designed for high order wavefront correction in ground and space-based astronomical adaptive optics instruments.
Proceedings ArticleDOI
