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.

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.

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.

Thermomechanical characterization of a membrane deformable mirror

Applied Optics, 2008
A membrane deformable mirror has been investigated for its potential use in high-energy laser systems. Experiments were performed in which the deformable mirror was heated with a 1 kW incandescent lamp and the thermal profile, the wavefront aberrations, and the mechanical displacement of the membrane were measured.
