New techniques for high-resolution imaging and high-precision wavefront sensing via masked-aperture interferometry
Nithyanandan Thyagarajan, Bojan Nikolic, Chris Carilli +2
The paper presents masked‑aperture interferometry techniques that measure both amplitude and phase of wavefront distortions to achieve nanometre‑scale wavefront sensing and sub‑arc…
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…
A New Method for Wavefront Sensing using Optical Masking Interferometry
C. L. Carilli, L. Torino, B. Nikolic +2
Wave front sensing of the surface of equal phase for a propagating electromagnetic wave is a vital technology in fields ranging from real time adaptive optics, to high accuracy met…
