Geometric phase interferometer
WebJul 1, 2004 · Geometric phase is very useful in constructing a nulling interferometer owing to its achromaticity and adjustability. These properties will be advantageous to a multi-element nulling interferometer and internal modulation where the nulled outputs with proper phase shifts are recombined so as to modulate a transmission map on the sky to ...

WebA vibration-insensitive, single-shot phase-calibration method for phase-only spatial light modulators (SLM) is reported. The proposed technique uses a geometric phase lens to form a phase-shifting radial shearing interferometer to enable common-path measurements. This configuration has several advantages: (a) unlike diffraction-based …

This is at the heart of geometric quantum computation that has been … WebA stable quadrature phase bias is highly demanded in the balanced Sagnac interferometer to achieve sufficient detection sensitivity and unambiguity. We demonstrate a straightforward and effective quadrature phase locking technique in a free-space balanced Sagnac interferometer by using a dual-loop, one for sensing and the other for bias feedback. …
WebDec 9, 2024 · Closure phase is the phase of a closed-loop product of correlations in a $\\ge 3$-element interferometer array. Its invariance to element-based phase corruption makes it invaluable for interferometric applications that otherwise require high-accuracy phase calibration. However, its understanding has remained mainly mathematical and limited to … WebFor example, in a Mach-Zehnder interferometer we are only sensitive to the phase of the laser at the time that photons are transferred, and all other phase terms cancel out. We therefore use the laser like a ruler to measure exactly how fast the atoms accelerate. As another example, a simultaneous conjugate Ramsey-Borde interferometer geometry ...
