Answer:

The correct answer to the following question will be "Adaptive Optics".

Explanation:

AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.

It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.

Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.

Therefore, Adaptive Optics is the right answer.
