Fast Iterative Tomographic Wave-front Estimation with Recursive Toeplitz Reconstructor Structure for Large Scale Systems
Yoshito H. Ono, Carlos Correia, Rodolphe Conan +3
Tomographic wave-front reconstruction is the main computational bottleneck to realize real-time correction for turbulence-induced wave-front aberrations in future laser-assisted to…
Modelling astronomical adaptive optics performance with temporally-filtered Wiener reconstruction of slope data
Carlos M. Correia, Charlotte Z. Bond, Jean-François Sauvage +3
We build on a long-standing tradition in astronomical adaptive optics (AO) of specifying performance metrics and error budgets using linear systems modeling in the spatial-frequenc…
Using Site Testing Data for Adaptive Optics Simulations
Glen Herriot, David Andersen, Rod Conan +8
Astronomical Site testing data plays a vital role in the simulation, design, evaluation and operation of adaptive optics systems for large telescope. We present the example of TMT…
Characterisation of the influence function non-additivities for a 1024-actuator MEMS deformable mirror
Celia Blain, Rodolphe Conan, Colin Bradley +2
In order to evaluate the potential of MEMS deformable mirrors for open-loop applications, a complete calibration process was performed on a 1024-actuator mirror. The mirror must be…
Radial thresholding to mitigate Laser-Guide-Star aberrations on Centre-of-Gravity-based Shack-Hartmann wavefront sensors
Olivier Lardiere, Rodolphe Conan, Colin Bradley +2
Sodium Laser Guide Stars (LGSs) are elongated sources due to the thickness and the finite distance of the sodium layer. The fluctuations of the sodium layer altitude and atom densi…
