On-sky binary source hypothesis testing beyond the diffraction limit using spatial mode demultiplexing based detection
John S. Wallis, Ayden S. McCann, Joshua J. Collier +4
Improving the resolution of telescope systems will provide the opportunity to study new physical phenomena in previously unobserved environments. Spatial mode de-multiplexing (SPAD…
Commissioning of the TeraNet Optical Ground Station Network
Sascha Schediwy, Aliesha Aden, Benjamin Dix-Matthews +13
TeraNet is a new three-node OGS network that has been established in Western Australia. The network is built to support a broad range of space missions operating between LEO and th…
Uplink Pre-Compensation for Ground-to-Space Optical Communications Using Downlink Tomographic Reconstruction
Alex Frost, Nicolas Maron, Shane Walsh +3
Uplink pre-compensation in ground-to-satellite optical links remains a problem, with an appropriate measurement of the wavefront error in the uplink path often not being available.…
Optimal design of small aperture optical terminals for free-space links
Alex M. Frost, Benjamin P. Dix-Matthews, Shane M. Walsh +2
We present the generalised design of low-complexity, small aperture optical terminals intended for kilometre-scale, terrestrial, free-space laser links between fixed and dynamic ta…
Free Space Optical Frequency Comparison Over Rapidly Moving Links
Shawn M. P. McSorley, Benjamin P. Dix-Matthews, Alex M. Frost +5
The comparison of optical reference frequency signals over free-space optical links is limited by the relative motion between local and remote sites. For ground to low earth orbit…
