Long baseline optical interferometric imaging with active phase stabilization
Joshua J. Collier, Leuca Patmore, John S. Wallis +3
The paper demonstrates active phase stabilization of a 170 km fiber‑based optical interferometer, using quantum‑optimal measurement techniques to achieve imaging resolution four ti…
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…
Relative Wavefront Error Correction Over a 2.4 km Free-Space Optical Link via Machine Learning
Nathan K. Long, Benjamin P. Dix-Matthews, Alex Frost +4
In coherent optical communication across turbulent atmospheric channels, reference beacons can be multiplexed with information-encoded signals during transmission. In this case, it…
Phase stabilization for long baseline interferometry of incoherent optical sources
Joshua J. Collier, David R. Gozzard, John S. Wallis +1
The maximum baseline, and therefore resolution, of optical astronomical interferometers is limited by attenuation and phase noise within the optical path between the apertures and…
Rapidly Tunable Synthetic Wavelength Ranging with an RFSoC
Shawn M. P. McSorley, Benjamin P. Dix-Matthews, Andrew M. Lance +2
Measurements of optical range and time-of-flight are crucial for a variety of high-precision technologies. Competitive optical measurement techniques have been developed that balan…
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…
