Wavefront prediction using artificial neural networks for open-loop Adaptive Optics
Xuewen Liu, Tim Morris, Chris Saunter +3
Latency in the control loop of adaptive optics (AO) systems can severely limit performance. Under the frozen flow hypothesis linear predictive control techniques can overcome this,…
Generating Artificial Reference Images for Open Loop Correlation Wavefront Sensors
M. J. Townson, G. D Love, C. D. Saunter
Shack-Hartmann wavefront sensors for both solar and laser guide star adaptive optics (with elongated spots) need to observe extended objects. Correlation techniques have been succe…
Dynamic lens and monovision 3D displays to improve viewer comfort
Paul V. Johnson, Jared A. Q. Parnell, Joowan Kim +3
Stereoscopic 3D (S3D) displays provide an additional sense of depth compared to non-stereoscopic displays by sending slightly different images to the two eyes. But conventional S3D…
Improved shift estimates on extended Shack-Hartmann wavefront sensor images
M. J. Townson, A. Kellerer, C. D. Saunter
An important factor which affects performance of solar adaptive optics (AO) systems is the accuracy of tracking an extended object in the wavefront sensor. The accuracy of a centre…
Shack-Hartmann sensor improvement using optical binning
Alastair Basden, Deli Geng, Dani Guzman +3
We present a design improvement for a recently proposed type of Shack-Hartmann wavefront sensor that uses a cylindrical (lenticular) lenslet array. The improved sensor design uses…
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…
