Speckle observations of binary stars with a 0.5 m telescope
, 2005 We present 36 observations of 17 visual binaries of moderate separation (range from 0.15'' to 0.79'') made with the 50 cm Cassegrain telescope of the Jagiellonian University in Cracow. The speckle interferometry technique was combined with modest optical

Optically trapped atom interferometry using the clock transition of large Rb-87 Bose-Einstein condensates [PDF]
, 2004 We present a Ramsey-type atom interferometer operating with an optically trapped sample of 10^6 Bose-condensed Rb-87 atoms. The optical trap allows us to couple the |F =1, mF =0>\rightarrow |F =2, mF =0> clock states using a single photon 6.8GHz ...

Hybrid Magnetoactive Soft Elastomers: Material Development Toward Application in Diaphragm Pumps
Advanced Materials Technologies, EarlyView.Hybrid magnetoactive soft elastomeric membranes are developed by combining two different types of magnetic particles. The membranes exhibit distinct mechanical, magnetic and thermal properties owing to the unique characteristics of the two magnetic particles.

Differential SAR interferometry using corner reflectors
IEEE International Geoscience and Remote Sensing Symposium, 2003 The differential InSAR technique has the potential for monitoring centimetre-scale ground motion in an accurate and cost-effective manner. Probably the most important limiting factor in the application of InSAR is temporal change in the complex reflectivity of the ground surface during the period between radar acquisitions.

Large Scale 3D Image Reconstruction in Optical Interferometry
, 2015 Astronomical optical interferometers (OI) sample the Fourier transform of the intensity distribution of a source at the observation wavelength. Because of rapid atmospheric perturbations, the phases of the complex Fourier samples (visibilities) cannot be

Active Control of Laser Wavefronts in Atom Interferometers
, 2017 Wavefront aberrations are identified as a major limitation in quantum sensors. They are today the main contribution in the uncertainty budget of best cold atom interferometers based on two-photon laser beam splitters, and constitute an important limit ...
