We propose a source of multimode squeezed light that can be used for superresolving microscopy. This source is an optical parametric amplifier with a properly chosen diaphragm on its output and a Fourier lens. We demonstrate that such an arrangement produces squeezed prolate spheroidal waves that are the eigenmodes of the optical imaging scheme used in microscopy and discuss the conditions of t...

Mapping the potential landscape with high spatial resolution is crucial for quantum technologies based on ultracold atoms. Yet, imaging optical dipole traps challenging because purely methods, commonly used to profile laser beams in free space, are not applicable vacuum. In this work, we demonstrate precise in-situ of by probing a hyperfine transition Ramsey interferometry. Thereby, obtain an a...

High-resolution, wide-field-of-view airborne imaging produces large optical systems and data streams. Significant simplification is possible if motion detection, rather than full imaging, is the goal. We consider a static, compressive-sensing architecture for this problem. c © 2010 Optical Society of America OCIS codes: (110.1758) Computational imaging; (110.4153) Motion estimation and optical ...
