Progress in quantum telescopes
David R. Gozzard, Fiona H. Panther, Andrew G. White
Classically, the angular resolution of a telescope is limited by its diffraction limit: the ratio of its observing wavelength to its diameter. Developments in quantum information t…
Long baseline optical interferometric imaging with active phase stabilization
Joshua J. Collier, Leuca Patmore, John S. Wallis +3
Astronomical observations allow us to better our understanding of the universe. As we observe smaller and more distance features, we run into the diffraction limit of our observati…
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…
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…
Super resolving binary-source hypothesis testing with a double-clad fiber coupler
John S. Wallis, David R. Gozzard, Alex M. Frost +3
We present a technique for binary spatial mode demultiplexing, using a double-clad fiber coupler as an optical mode sorter, for hypothesis testing for one or two point sources in a…
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…
