WHAT DOES ACTIVE OPTICS MEAN IN ENGLISH?

active optics

Active optics

Active optics is a technology used with reflecting telescopes developed in the 1980s, which actively shapes a telescope's mirrors to prevent deformation due to external influences such as wind, temperature, mechanical stress. Without active optics, the construction of 8 metre class telescopes is not possible, nor would telescopes with segmented mirrors be feasible. This method is used by, among others, the Nordic Optical Telescope, the New Technology Telescope, the Telescopio Nazionale Galileo and the Keck telescopes, as well as all of the largest telescopes built in the last decade. Active optics is not to be confused with adaptive optics, which operates at a shorter timescale and corrects different distortions.

Definition of active optics in the English dictionary

The definition of active optics in the dictionary is a system to compensate for any deformation caused by gravity in the surface accuracy and alignment of the mirrors of an astronomical telescope by means of actuators that control the movable mirror supports.
