  • tehnoloogia, mis jälgib ja muudab vaatluste ajal teleskoobi peegli kuju, et vähendada välistest teguritest (temperatuur, teleskoobi asend, mehaanilised pinged jne.) tingitud moonutusi
  • technology used with reflecting telescopes, which actively shapes a telescope's mirrors to prevent deformation due to external influences such as wind, temperature, mechanical stress
    Good to know
    • Not to be confused with adaptive optics [ IATE:1900313 ], which operates at a shorter timescale and corrects atmospheric distortions.

active optics
Usage examples
  • However, as plans were developed in the 80s to enhance light-collecting power by building telescopes with primary mirrors well above 4 m in diameter, it became clear that conventional methods of maintaining image quality were ruled out by cost and structure weight limitations. As a result,the new technique of Active Optics has been developed for medium or large telescopes, with Image quality optimised automatically by means of constant adjustments by in-built corrective optical elements operating at fairly low temporal frequency ~ 0.05 Hz or less.
