En géométrie, il existe trois types de paraboloïdes : hyperbolique, elliptique et celui de révolution, qui est obtenu par la rotation d’une parabole autour de son axe. Dans le domaine de l’optique, le miroir parabolique a la forme d’un paraboloïde de révolution.

Active optics is a relatively new technology for reflecting telescopes developed in the 1980s, which has more recently enabled the construction of a generation of telescopes with 8 metre primary mirrors. Active optics works by "actively" adjusting the telescope's mirrors. This method is used by, among others, the Nordic Optical Telescope, the New Technology Telescope and the Keck telescopes, as well as all of the largest telescopes built in the last decade. 3, record 4, English, - active%20optics

Pour gagner en précision, il faut d’une part augmenter le nombre de traits au mm [de la trame] et se rapprocher du foyer. Dans ce cas les phénomènes de diffraction sont prépondérants et rendent l'interprétation de l'image impossible.
