High angular resolution neutron interferometry

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2011
The currently largest perfect-crystal neutron interferometer with six beam splitters and two interference loops offers novel applications in neutron interferometry. The two additional lamellas can be used for quantitative measurements of a phase shift due to crystal diffraction in the vicinity of a Bragg condition.

Compact multi-aperture imaging with high angular resolution [PDF]

open access: yesJournal of the Optical Society of America A, 2015
Previous reports have demonstrated that it is possible to emulate the imaging function of a single conventional lens with an N×N array of identical lenslets to provide an N-fold reduction in imaging-system track length. This approach limits the application to low-resolution imaging.

High-resolution digital holography utilized by the subpixel sampling method [PDF]

open access: yes, 2011
A novel (to our knowledge) approach for resolution improvement in digital holography is presented in this paper. The proposed method is based on recording the incoming interference field on a complementary metal-oxide semiconductor (CMOS) camera with ...

Fiber tracking in q-ball fields using regularized particle trajectories [PDF]

open access: yes, 2005
Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel.

Waveguide theory applied to optically measured angular sensitivities of fly photoreceptors [PDF]

open access: yes, 1984
Farfield radiation patterns of single ommatidia of the fly, Calliphora erythrocephala, have been photographed. Clear radiation patterns of the first and the second waveguide mode have been observed. According to theory, the shape of the (optical) angular

Observation of Cosmic Microwave Background Polarization with BICEP [PDF]

open access: yes, 2009
Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the ...
