Adaptive optics
| Glossary Of Laser Terminology |
Recent advances in deformable mirror technology and laser guide stars allows most of the distortion produced by the atmosphere to be removed. this results in near diffraction-limited performance of ground-based receiving telescopes, giving image quality similar to that produced by the hubble space telescope.

Adaptive, английский
- Адаптивный; настраиваемый
- A general modifer used to describe systems such as neural networks or other dynamic control systems that can learn or adapt from data in use. adaptive fuzzy associative memory (afam) an fuzzy associative memory that is allowed to adapt to time varying input. adaptive resonance theory (art) a class of neural networks based on neurophysiologic models for neurons. they were invented by stephen grossberg in 1976. art models use a hidden layer of ideal cases for prediction. if an input case is sufficiently close to an existing case, it ``resonates" with the case; the ideal case is updated to incorporate the new case. otherwise, a new ideal case is added. arts are often represented as having two layers, referred to as an f1 and f2 layers. the f1 layer performs the matching and the f2 layer chooses the result. it is a form of cluster analysis. see also: ftp:://ftp.sas.com/pub/neural/faq2.html, http://www.wi.leidenuniv.nl/art/

Technology, английский
- The use of tools and knowledge to meet human needs.

- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).
Distortion, английский
- A drying defect caused by the differential shrinkage along the three axes of a piece of wood. distortion may take the form of cup, bow, twist, spring or diamonding.
- Искажение, дисторсия
- The deviation of the received signal waveform from that of the original transmitted waveform.
- Nonproportional representation of an original.
- Искажение (формы); коробление
- Нарушение достоверности информации, см. bias; error, deviation, misreporting запасы (сырья и материалов), см. stocks with industrial consumers; reserves for manufacturing purposes al consumers; reserves for manufacturing purposes 61,. distributed stocks (of raw materials) — производственные запасы (сырья и материалов), см. stocks with industrial consumers; reserves for manufacturing purposes.
- An undesired change in wave form of a signal in the course of its passage through a transmission system.
- An off-axis lens aberration that changes the geometric shape of the image due to a variation of focal length as a function of field angle.
- Any changing of line, form, or even light by photographic materials, such as lenses, films, or filters. though most designers do all they can to eliminate distortion from lenses, most photographers take the "if you can`t beat `em, join `em" approach and exploit it wherever they find it; they use distortion as part of their visual expression.
- An aberration which occurs as light rays move from the center of the lens toward the periphery. as rays approach the edge, the lens’s increasing magnification causes a distorting of the image.
- The act of twisting part of the body out of its usual shape
- Искажение

- An intentional desired, or unintentional unwanted, change in the audio waveform, causing a raspy or edgy sound quality.
