Photonics Spectra
Jun 2010
Piezosystem Jena Inc. of Hopedale, Mass., has awarded a $1500 scholarship to Andre Denio of California State University, Northridge, to support his research into developing computer algorithms that control piezoelectrically driven mirrors. The mirrors are part of an adaptive optical system being developed for ground-based telescopes.

adaptive optics
Optical components or assemblies whose performance is monitored and controlled so as to compensate for aberrations, static or dynamic perturbations such as thermal, mechanical and acoustical disturbances, or to adapt to changing conditions, needs or missions. The most familiar example is the "rubber mirror,'' whose surface shape, and thus reflective qualities, can be controlled by electromechanical means. See also active optics; phase conjugation.
A smooth, highly polished surface, for reflecting light, that may be plane or curved if wanting to focus and or magnify the image formed by the mirror. The actual reflecting surface is usually a thin coating of silver or aluminum on glass.
An afocal optical device made up of lenses or mirrors, usually with a magnification greater than unity, that renders distant objects more distinct, by enlarging their images on the retina.
