Shape memory composite deformable mirrors

SPIE Proceedings, 2009
This paper deals with some of the critical aspects regarding Shape Memory Composite (SMC) design: firstly some technological aspects concerning embedding technique and their efficiency secondarily the lack of useful numerical tools for this peculiar design.

Tiny Multilayer Deformable Mirrors

2006 International Workshop on Laser and Fiber-Optical Networks Modeling, 2006
Formation of the given laser beam intensity and phase is an important practical and scientific problem. Bimorph flexible mirror is one of the most widely used devices for this purpose. We present a new approach of multilayer bimorph mirrors and a numerical model to simulate them, based on the finite elements method.

Deformable primary mirror for a space telescope

Applied Optics, 1982
A 4-m aperture deformable primary mirror has been designed with the mirror and its supports integrated into a single structure. The integrated active mirror's minimal weight makes it desirable for a space telescope as well as a terrestrial application.

MEMS arrays for deformable mirrors

SPIE Proceedings, 1995
A new class of silicon-based deformable mirror for use in optical applications such as adaptive optical systems and optical correlators is being built. The mirror will be a massively parallel system of electrostatically controlled, interconnected microactuators that can be coordinated to achieve precise actuation and control at a macroscopic level.

Congenital mirror hand deformity.

Genetic counseling (Geneva, Switzerland), 2012
Ulnar dimelia or commonly called mirror hand is a rare congenital anomaly of upper extremity characterized by duplication of ulna, absence of the radius with symmetrical polydactyly. This anomaly may be associated with shoulder dislocation, fibular dimelia, idiopathic scoliosis, cirrhosis, pyloric hypertrophy or polycystic kidney.

Magnetic Fluid Deformable Mirrors

2012
The number of new adaptive optics applications has soared during the last decade, demonstrating the need for low-cost, high-stroke deformable mirrors with a large number of actuators. Magnetic fluid deformable mirrors (MFDMs) were proposed a few years ago as an alternative to conventional membrane deformable mirrors used in wavefront correctors. Though

Deformable Mirrors — The Hands

2009
A lot of people use the terms deformable mirror and adaptive optics interchangeably -€” "€œLet's put adaptive optics in the beam."€ -€” with no regard for the fact that the singular form of the noun optics, -€” "€œthe adaptive optic goes right before the beamsplitter"€ -€” is almost never used anymore.

Dynamic response of ferrofluidic deformable mirrors

Applied Optics, 2008
Ferrofluids can be used to make deformable mirrors having highly interesting characteristics (e.g., extremely large strokes and low costs). Until recently, such mirrors were thought to be restricted to corrections of frequencies lower than 10 Hz, thus limiting their usefulness.

Driver ASICs for Deformable Mirrors

Imaging and Applied Optics 2015, 2015
We have developed three types of ASICs to be directly integrated with deformable mirrors, eliminating almost all cables. These will enable very compact adaptive optics systems in space with low power consumption.
