Key Concepts

Adaptive Optics

Adaptive optics is a technology used in optical systems to improve image quality by dynamically correcting distortions in real-time. It adjusts the incoming light wavefront, compensating for aberrations typically caused by disturbances such as atmospheric turbulence, and is particularly vital for ground-based telescopes to achieve near-space-quality resolution.

Atmospheric Turbulence

Atmospheric turbulence refers to the random fluctuations in the Earth's atmosphere that cause variations in the refractive index. These fluctuations distort the path of light from celestial objects, leading to blurred and less defined images when observed through telescopes, especially those located on the ground.

Deformable Mirrors

Deformable mirrors are a critical component of adaptive optics systems. They are engineered to change their shape in response to control signals based on real-time measurements of wavefront distortions, allowing the optical system to compensate for atmospheric blurring and significantly enhance the spatial resolution of the captured images.
