The Durham ELT adaptive optics simulation platform
Alastair Basden, Timothy Butterley, Richard Myers +1
Adaptive optics systems are essential on all large telescopes where image quality is important. These are complex systems with many design parameters requiring optimisation before…
Adaptive optics simulation performance improvements using reconfigurable logic
Alastair Basden
A technique used to accelerate an adaptive optics simulation platform using reconfigurable logic is described. The performance of parts of this simulation have been improved by up…
Acceleration of adaptive optics simulations using programmable logic
A. G. Basden, F. Assemat, T. Butterley +3
Numerical Simulation is an essential part of the design and optimisation of astronomical adaptive optics systems. Simulations of adaptive optics are computationally expensive and t…
Improvements for group delay fringe tracking
A. G. Basden, D. F. Buscher
Group delay fringe tracking using spectrally-dispersed fringes is suitable for stabilising the optical path difference in ground-based astronomical optical interferometers in low l…
Low light level CCDs and visibility parameter estimation
A. G. Basden, C. A. Haniff
Recently, low light level charge coupled devices (L3CCDs) capable of on-chip gain have been developed, leading to sub-electron effective readout noise, allowing for the detection o…
Photon counting strategies with low light level CCDs
A. G. Basden, C. A. Haniff, C. D. Mackay
Low light level charge coupled devices (L3CCDs) have recently been developed, incorporating on-chip gain. They may be operated to give an effective readout noise much less than one…
