Internal reflection sensors with high angular resolution
Applied Optics, 1996We discuss the use of total internal reflection for the production of sensors with high angular resolution. These sensors are intended for measurement of the angle between a sensor's axis and the direction to a source of radiation or reflecting object.

Demons registration of high angular resolution diffusion images
2010 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2010In this work we present a method for non-rigid registration of high angular resolution diffusion imaging (HARDI) datasets that are modeled by a field of antipodally symmetric spherical functions, represented by their expansion in the real spherical harmonic (RSH) basis.

X-ray photoelectron diffraction at high angular resolution
Physical Review B, 1987We present x-ray photoelectron diffraction (XPD) measurements at an angular resolution of \ensuremath{\sim}\ifmmode\pm\else\textpm\fi{}1.0\ifmmode^\circ\else\textdegree\fi{} which is much higher than in any prior study. Emission from the Ni 2${p}_{3/2}$ core level of Ni(001) under Al K\ensuremath{\alpha} excitation is considered.

High Angular Resolution Stellar Interferometry
Publications of the Astronomical Society of Australia, 1976The history and achievements of interferometric angular diameter measurements have been reviewed recently by Hanbury Brown (1974) and only a brief outline will be given here. As the title is intended to imply, the present discussion will be limited to interferometry involving baselines in excess of telescope aperture diameters.

X-ray astronomy with ultra-high-angular resolution
SPIE Proceedings, 2004We present new schemes for a next-generation X-ray telescope for the energy range between approximately 1 and 10 keV providing an angular resolution of at least 1 milli-arcsec. Its technology will be based on diffractive transmission optics, e.g. Fresnel zone plates and their derivatives.

High Angular-Resolution Techniques
2009This chapter examines the synthesis and performance of one-dimensional (1D) and two-dimensional (2D) phased arrays and their application in sonar and radar before considering the elegant algorithms for Doppler beam sharpening and synthetic aperture radar (SAR) that can be used to produce a 'beam' with no divergence at all.

High Angular Resolution Diffusion Imaging
2016The development of diffusion tensor imaging (DTI) over two decades ago was a pivotal moment in the field of diffusion Magnetic Resonance Imaging (MRI), offering for the first time a glimpse into the connectivity of brain white matter in a completely noninvasive manner.

High Angular Resolution Observations of Disks
2007In this lecture, I will review the properties of protoplanetary disks as derived from high angular resolution observations. I discuss how the combination of several different high angular resolution techniques allow us to probe different regions of the disk and to derive the properties of the dust when combined with sophisticated disk models.

Themistocle: A high angular resolution Cerenkov light detector
Nuclear Physics B - Proceedings Supplements, 1989The present paper is a description of a high resolution Cerenkov air shower detector equipped with 18 mirrors which will be located in a first step in the French Pyrenees mountains on a site called THEMIS. The first experimental aims are to show that reasonable ultra-high energy ˠ fluxes can be observed and that an angular resolution of 0.5 mrad could ...

Imaging transient events at high angular resolution
SPIE Proceedings, 2016Resolving the spatial structure of transient events provides insights into their physical nature and origin. Recent observations using long baseline optical/infrared interferometry have revealed the size, shape, and angular expansion of bright novae within a few days after their outbursts.
