Hybrid AI optimization for sensorless adaptive optics

Ivan Agostinelli, Alessandro Di Filippo, Lorenzo Paonni, Mauro Centrone et autres

This work presents an AI-augmented, fully sensorless adaptive optics (AO) framework designed to overcome atmospheric turbulence and reduce the computational burden of real-time correction. The system builds upon ZARA, a metaheuristic wavefront-optimization algorithm that iteratively adjusts Zernike coefficients using a Fourier-based image-quality …

The crucial role of the laser pointing camera in the CANAPY-ALASCA project

Mauro Centrone, David Alaluf, Roberto Biasi, Domenico Bonaccini Calia et autres

The role played by the LPC (Laser Pointing Camera, produced by ASTREL Instruments in collaboration with INAF-OAR) within the CANAPY-ALASCA project (an experimental LGS-AO system, achieved thanks to a synergy between INAF, ESO, ESA, Microgate, Durham University, IAC) is described, emphasizing his …

Correcting atmospheric intensity fluctuations using a laser guide star

Kathryn E. Hartley, James C. Osborn, Domenico Bonaccini Calia, Felipe Pedreros Bustos et autres

The negative effects of the Earth’s atmosphere severely limits ground based high precision photometry. Scintillation noise cannot easily be corrected as it is produced by high altitude turbulence, and therefore the range of angles over which it is correlated is very small. …

Using LGS to calibrate scintillation for time resolved photometry

Kathryn E. Hartley, James C. Osborn, Domenico Bonaccini Calia, Felipe Pedreros Bustos et autres

We present a new technique to correct photometric noise produced by atmospheric effects by using a laser guide star, projected along the same line of sight as the astronomical target, as a comparison star.
