New techniques for high-resolution imaging and high-precision wavefront sensing via masked-aperture interferometry
Nithyanandan Thyagarajan, Bojan Nikolic, Chris Carilli +2
Achieving high-angular-resolution imaging on subarcsecond scales is fundamentally limited by wavefront aberrations imparted by the propagation medium and by optical elements along…

Two-dimensional Light Beam Shape Characterization using Interferometric Closure Amplitudes
Nithyanandan Thyagarajan, Bojan Nikolic, Chris Carilli +2
We introduce a novel technique using closure amplitudes, inspired by radio interferometry, to determine with high angular resolution the two-dimensional profile of a light beam usi…
