A new approach to stellar image correction for atmospherically degraded images

Chinnappan, V (Indian Institute of Astrophysics, 2006-08)

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, ...
Progressive prediction of turbulence using wave-front sensor data in adaptive optics using data mining

Vyas, A; Roopashree, M. B; Prasad, B. R (Macmillan Publishers India Ltd., 2009)

Nullifying the servo bandwidth errors improves the strehl ratio by a substantial quantity in adaptive optics systems. An effective method for predicting atmospheric turbulence to reduce servo bandwidth errors in real time ...
