Automated wind velocity profiling from adaptive optics telemetry (2019)
Journal Article
Laidlaw, D. J., Osborn, J., Morris, T. J., Basden, A. G., Gendron, E., Rousset, G., …Wilson, R. W. (2020). Automated wind velocity profiling from adaptive optics telemetry. Monthly Notices of the Royal Astronomical Society, 491(1), 1287-1294. https://doi.org/10.1093/mnras/stz3062

Ground-based adaptive optics (AO) systems can use temporal control techniques to greatly improve image resolution. A measure of wind velocity as a function of altitude is needed to minimize the temporal errors associated with these systems. Spatio-te...

Optimizing the accuracy and efficiency of optical turbulence profiling using adaptive optics telemetry for extremely large telescopes (2018)
Journal Article
Laidlaw, D. J., Osborn, J., Morris, T. J., Basden, A. G., Beltramo-Martin, O., Butterley, T., …Wilson, R. W. (2018). Optimizing the accuracy and efficiency of optical turbulence profiling using adaptive optics telemetry for extremely large telescopes. Monthly Notices of the Royal Astronomical Society, 483(4), 4341-4353. https://doi.org/10.1093/mnras/sty3285

Advanced adaptive optics (AO) instruments on ground-based telescopes require accurate knowledge of the atmospheric turbulence strength as a function of altitude. This information assists point spread function reconstruction, AO temporal control techn...

Modelling synthetic atmospheric turbulence profiles with temporal variation using Gaussian mixture model (2018)
Journal Article
Jia, P., Osborn, J., Kong, L., Laidlaw, D., Li, C., Farley, O., & Xue, G. (2018). Modelling synthetic atmospheric turbulence profiles with temporal variation using Gaussian mixture model. Monthly Notices of the Royal Astronomical Society, 480(2), 2466-2474. https://doi.org/10.1093/mnras/sty1951

The atmospheric turbulence profile plays a very important role for performance evaluation of wide-field adaptive optic systems. Since the atmospheric turbulence is evolving, the turbulence profile will change with time. To better model the temporal v...

Optical turbulence profiling with Stereo-SCIDAR for VLT and ELT (2018)
Journal Article
Osborn, J., Wilson, R., Sarazin, M., Butterley, T., Chacon, A., Derie, F., …Townson, M. (2018). Optical turbulence profiling with Stereo-SCIDAR for VLT and ELT. Monthly Notices of the Royal Astronomical Society, 478(1), 825-834. https://doi.org/10.1093/mnras/sty1070

Knowledge of the Earth’s atmospheric optical turbulence is critical for astronomical instrumentation. Not only does it enable performance verification and optimisation of existing systems but it is required for the design of future instruments. As a...
