A Robust Interferometry Against Imperfections Base on Weak Value Amplification [PDF]
Phys. Rev. A 97, 063818 (2018), 2018 The optical interferometry has been widely used in various high precision applications. Usually, the minimum precision of an interferometry is limited by various technique noises in practice. To suppress such kind of noises, we propose a novel scheme, which combines the weak measurement with the standard interferometry. The proposed scheme dramatically

Interferometry with Vortices [PDF]
International Journal of Optics, 2012 Interference of optical beams with optical vortices is often encountered in singular optics. Since interferometry makes the phase observable by intensity measurement, it brings out a host of applications and helps to understand the optical vortex. In this article we present an optical vortex interferometer that can be used in optical testing and has ...

Coincidence landscapes for polarized bosons [PDF]
Phys. Rev. A 98, 013817 (2018), 2018 Passive optical interferometry with single photons injected into some input ports and vacuum into others is enriched by admitting polarization, thereby replacing the scalar electromagnetic description by a vector theory, with the recent triad phase being a celebrated example of this richness.
