Digital interferometric demodulation of Placido mires applied to corneal topography
Digital interferometric demodulation Placido mires corneal topography Optics

This paper presents a novel digital interferometric method to demodulate Placido fringe patterns. This is a synchronous method which uses a computer-stored conic-wavefront as demodulating reference. H...

Efficient self-interference of single-photons emitted by a sideband-cooled Barium ion is demonstrated. First, the technical tools for performing efficient coupling to the quadrupolar transition of a s...
Negative Backaction Noise in Interferometric Detection of a Microlever
Negative Backaction Noise Interferometric Detection Microlever

Abstract: Interferometric detection of mirror displacements is intrinsically limited by laser shot noise. In practice, however, it is often limited by thermal noise. Here we report on an experiment pe...

We study the use of atom interferometers as detectors for gravitational waves in the mHz - Hz frequency band, which is complementary to planned optical interferometers, such as LIGO and LISA. We descr...
