Atmospheric optical turbulence analysis in London’s financial district (2023)
Presentation / Conference Contribution
Westerby-Griffin, L., Osborn, J., Farley, O. J. D., Griffiths, R., & Love, G. D. (2023, January). Atmospheric optical turbulence analysis in London’s financial district. Presented at Free-Space Laser Communications XXXV, San Francisco, United States

Atmospheric optical turbulence causes signal loses in laser propagation. Here we present vertical measurements of optical turbulence taken in London’s financial district. Additionally, we demonstrate a method of modelling atmospheric states in simula... Read More about Atmospheric optical turbulence analysis in London’s financial district.

Conjugate-plane photometry: reducing scintillation in ground-based photometry (2011)
Journal Article
Osborn, J., Wilson, R. W., Dhillon, V., Avila, R., & Love, G. D. (2011). Conjugate-plane photometry: reducing scintillation in ground-based photometry. Monthly Notices of the Royal Astronomical Society, 411(2), 1223-1230. https://doi.org/10.1111/j.1365-2966.2010.17759.x

High-precision fast photometry from ground-based observatories is a challenge due to intensity fluctuations (scintillation) produced by the Earth's atmosphere. Here we describe a method to reduce the effects of scintillation by a combination of pupil... Read More about Conjugate-plane photometry: reducing scintillation in ground-based photometry.
