Gaussian phase autocorrelation as an accurate compensator for FFT-based atmospheric phase screen simulations
Sorabh Chhabra, Jyotirmay Paul, A. N. Ramaprakash +1
Accurately simulating the atmospheric turbulence behaviour is always challenging. The well-known FFT based method falls short in correctly predicting both the low and high frequenc…
A generalized approach to compensate for low and high frequency errors in FFT based phase screen simulations
Sorabh Chhabra, Jyotirmay Paul, Anamparambu N. Ramaprakash +1
Fast Fourier Transform based phase screen simulations give accurate results only when the screen size () is much larger than the outer scale parameter (). Otherwise, they f…
Scalable Platform for Adaptive optics Real-time Control (SPARC) Part 1: Concept, Architecture and Validation
Avinash Surendran, Mahesh P. Burse, A. N. Ramaprakash +3
We demonstrate a novel architecture for Adaptive Optics (AO) control based on FPGAs (Field Programmable Gate Arrays), making active use of their configurable parallel processing ca…
