Coma
| Glossary of Diseases and Symptoms (Italiano-Inglese) |
- An off-axis lens aberration resulting from a variation of lens focal lengths as a function of aperture zone or annulus.
- A state of unconsciousness from which a person cannot be awakened by external stimuli comment: a coma can have many causes: head injuries, diabetes, stroke or drug overdose. a coma is often fatal, but a patient may continue to live in a coma for a long time, even several months, before dying or regaining consciousness.

- , искажение изображения в оптических системах, из-за чего точка предмета принимает вид несимметричного пятна.
- Один из видов аберраций оптической системы, в результате которой изображение точки, находящейся вне оптической оси имеет вид несимметричного пятна (по форме напоминающего запятую). комы вызвана неодинаковым преломлением лучей различными участками линзы.
- Тип аберраций, при котором нарушается симметрия широкого пучка лучей в меридиональном сечении.

Aberration, английский

- A term from optics that refers to anything affecting the fidelity of the image in regards to the original scene.
- A distortion of image quality or color rendition in a photographic image caused by optical limitations of the lens used for image capture. aberrations commonly show up in the form of halation around high-contrast portions of the image, or “smearing” of color toward the edges of the frame. aspheric lens surfaces and advanced lens coatings are often used in more expensive or complex lenses as a means of reducing aberrations. for more on this subject, see the explora article, “optical anomalies and lens corrections explained.”
- Any flaw introduced during the manufacturing or grinding of a spectacle lens that can result in image blur. it may be inherent in the lens design or may result from an error in processing.
- An action or growth which is not usual or expected
- An apparent change of place, or alteration of their mean position, in the fixed stars, caused by the earth`s orbital movement.— aberration of a planet signifies its progressive geocentric motion, or the space through which it appears to move, as seen from the earth, during the time which light occupies in passing from the planet to us.—crown of aberration is a spurious circle surrounding the proper disc of the sun.—constant of aberration, or amount of displacement in the sun`s longitude, arising from
- In celestial navigation, the apparent displacement of a heavenly body due to the observer’s motion.
Unconsciousness, английский
