Atmospheric turbulence degrades the image formed by ground-based telescopes. It causes the image to be spread over a large area known as the seeing-disk in a typical long exposure. In a short exposure, the image is spread ...

Atmospheric turbulence is a major problem when imaging is done with the help of optical telescopes. Adaptive Optics has played a major role in compensating the turbulence to give a near diffraction-limited image. Our ...
