Optical feeder links offer immense utility in meeting future communication demands—however, atmospheric turbulence limits their performance. This work targets this challenge through analyses of a bidirectional free-space optical communication (FSOC)...

Exploring atmospheric optical turbulence: observations across zenith angles (2024)
Journal Article
Beesley, L. F., Osborn, J., Wilson, R., Farley, O. J. D., Griffiths, R., & Love, G. D. (2024). Exploring atmospheric optical turbulence: observations across zenith angles. Applied Optics, 63(16), E48. https://doi.org/10.1364/ao.519063

We present measurements of the atmospheric optical turbulence as a function of zenith angle using two identical instruments, Shack-Hartmann Image Motion Monitors (SHIMMs), to measure atmospheric parameters concurrently. One instrument was pointed nea... Read More about Exploring atmospheric optical turbulence: observations across zenith angles.

A comparison of next-generation turbulence profiling instruments at Paranal (2024)
Journal Article
Griffiths, R., Bardou, L., Butterley, T., Osborn, J., Wilson, R., Bustos, E., …Otarola, A. (2024). A comparison of next-generation turbulence profiling instruments at Paranal. Monthly Notices of the Royal Astronomical Society, 529(1), 320 - 330. https://doi.org/10.1093/mnras/stae434

A six-night optical turbulence monitoring campaign has been carried at Cerro Paranal observatory in February and March, 2023 to facilitate the development and characterisation of two novel atmospheric site monitoring instruments - the ring-image next...
