The precision measurement of position has a long-standing tradition in physics. Cavendish's verification of the universal law of gravitation using a torsion pendulum, Perrin's confirmation of the atomic hypothesis via the precise measurement of the Brownia ...
Solar energy has seen tremendous advances in the past years. For thin film photovoltaics, which use less of the expensive semiconductor materials, insufficient light absorption can be a limiting factor. It is hoped that by using diffractive optics to impro ...
What is the actual information contained in light rays filling the 3-D world? Leonardo da Vinci saw the world as an infinite number of radiant pyramids caused by the objects located in it. Nowadays, the radiant pyramid is usually described as a set of ligh ...
A device for self-tracking a light source, including a focusing optical device configured to focus incoming light to a focal spot, an adaptive device configured to reflect the light of the focal spot and arranged to provide for a phase change at an area of ...
We investigate the transition of optical regimes of miniaturized optical systems using two canonical examples, where the refraction of light limits the system performance. A ball-lens and a solid immersion lens (SIL) are considered, whose refractive respon ...
In this paper, kinetic and potential energy transfers around a spectral test filter scale in direct numerical simulations of decaying stratified turbulence are studied in both physical and spectral domains. It is shown that while the domain-averaged effect ...
In a high-impedance communications interface, driver energy consumption is proportional to the number of signal transitions. For signals having three or more distinct levels, it is possible for a signal driver to salvage energy from some downward signal tr ...
Since its introduction in the mid-nineties, photoacoustic imaging of biological tissue has been one of the fastest growing biomedical imaging modality, and its basic principles are now considered as well established. In particular, light propagation in pho ...
We describe our observation of strongly oriented total electronic angular momentum J in O(P-3(2)), Ne(P-3(2)), and He(S-3(1)) atoms emerging from a bent magnetic multipole guide, as measured by resonant multiphoton ionisation. This was contrary to our expe ...
A method for the preparation of a sample comprising highly polarized nuclear spins is proposed, comprising at least the following steps: a) provision of molecules with 1,2-dione structural units and/or molecules with 2,5-diene-1,4-dione structural units in ...
