Continuously Deformable Mirrors
SPIE Proceedings, 1987Low spatial and temporal frequency correction of optical wavefronts can be achieved with continuously deformable mirrors that are being developed by the Atomic Vapor Laser Isotope Separation (AVLIS) Program at Lawrence Livermore National Laboratory. These devices are simple in design, low in cost, require relatively few actuators, and are capable of ...

SPIE Proceedings, 1992
This technical paper describes a new unique form of deformable mirror that was engineered, designed, and built at Hughes Danbury Optical Systems. This paper discusses the current state of the art, the requirements, configuration, and special features such as the choice of materials for the mirror, interchangeable actuators, cooling technique and ...

Elastic Deformation of Lightweight Mirrors
Applied Optics, 1973Results of analytical and experimental studies on the elastic deformation of lightweight mirrors under various support conditions are presented and compared. The analytical results were obtained using the finite-element method, which employs elements having stretching, bending, and twisting capability. Both structural deformation and deviation from the

Push-pull electrostatic deformable mirrors
SPIE Proceedings, 2008Deformable membrane mirrors have a lot of advantages if compared with other adaptive optics devices such as bimorph mirrors, liquid crystal modulators, and thermal mirrors. Their properties are good optical power, low cost, limited power consumption, achromaticity and a good dynamic behavior. Their use in technological applications is limited by the

Low-order adaptive deformable mirror
Applied Optics, 1998We report the main parameters of a nine-electrode bimorph piezoelectric adaptive mirror designed to correct low-order aberrations. We describe measurements of the control coefficients for defocus, astigmatism, pure coma, and spherical aberration of this mirror and the temperature stability of its profile.

High-speed deformable mirror system
Applied Optics, 1982A phase correction device has been developed for a high-power cw 10.6-microm laser beam using a water-cooled piezoelectric actuated deformable mirror system. It is the first HEL deformable mirror designed to provide dynamic high-speed wave front correction while simultaneously providing high-frequency phase modulation at any or all of its fifty-two ...

Mirror hand (ulnar dimelia) is an extremely rare congenital deformity in the upper extremity; only approximately seventy cases have been reported in the literature1,2 since the anomaly was first described in 1587 by Rueff3. The typical deformity consists of an absent radius, a duplication of the ulna, and polydactyly4,5. The elbow is generally stiff in

Congenital mirror hand deformity.
Genetic counseling (Geneva, Switzerland), 2012Ulnar 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.

Thermal Deformations of Solid Mirrors
Applied Optics, 1970The tensor equations of elasticity including temperature terms in nonorthogonal coordinates are presented in a form suitable for the method of dynamic relaxation. A nonorthogonal coordinate system that includes a wide class of circular solid mirrors or lenses is described.
