Adaptive Optics on a Budget

Facebook X LinkedIn Email
ALBUQUERQUE, N.M., July 9, 2007 -- A simple optical clamp that uses a single mirror functions as a sort of "poor man's" adaptive optics device. Adaptive optics, a system known for its computer control of subdivided, individually angled mirrors, is an efficient but expensive way to correct distortions in laser beams. The mirrors automatically adjust until an undistorted beam is obtained in a way formerly thought unachievable by a single large mirror. Jens Schwarz adjusts his group’s newly patented Sandia optical tool that precorrects for laser distortions. (Photo: Randy Montoya) The new device -- which has received a US...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
