Abstract:
Atmospheric turbulence is the main cause of image degradation and poor resolution at the focal plane of a perfectly made optical telescope. It is necessary to make corrective measures to improve the optical wave-front, thus, get improved resolution from the telescopes. This research work is an effort to understand the degradations caused by atmospheric turbulence, build an appropriate wave-front sensor to measure the errors in the wave-front and correct the wave-front in real time for our 2.34 M Vainu Bappu Telescope (VBT) at Vainu Bappu Observatory, Kavalur, keeping the cost as one of the main factors.
