Intrinsic Properties of Light and Corpuscles from Distant Sources.
Spectra of distant nebulae, compared with those of neighboring nebulae, are shifted toward the red by amounts which increase with the distance which the light has traveled. This fact indicates that we are confronted with a phenomenon which involves history on a large scale, history either of the universe as a whole, or history of some of its individual parts. Scientifically speaking, history me...
متن کاملNoise Reduction in Photometric Stereo with non-distant Light Sources
In classical photometric stereo, a Lambertian surface is illuminated from multiple distant point light-sources. In the present paper we consider nearby lightsources instead, so that the unknown surface, is illuminated by non-parallel beams of light. In continuous noiseless cases, the recovery of a Lambertian surface from non-distant illuminations, reduces to solving a system of non-linear parti...
متن کاملSurface extensions of 3T3 cells towards distant infrared light sources
Using a specially designed phase-contrast light microscope with an infrared spot illuminator we found that approximately 25% of 3T3 cells were able to extend pseudopodia towards single microscopic infrared light sources nearby. If the cells were offered a pair of such light sources next to each other, 47% of the cells extended towards them. In the latter case 30% of the responding cells extende...
متن کاملPhoton polarisation entanglement from distant dipole sources
It is commonly believed that photon polarisation entanglement can only be obtained via pair creation within the same source or via postselective measurements on photons that overlapped within their coherence time inside a linear optics setup. In contrast to this, we show here that polarisation entanglement can also be produced by distant single photon sources in free space and without the photo...
متن کاملMulti-photon entanglement from distant single photon sources on demand
We describe a scheme that allows for the generation of any desired N-photon state on demand. Under ideal conditions, this requires only N single photon sources, laser pulses and linear optics elements. First, the sources should be initialised with the help of single-qubit rotations and repeat-until-success two-qubit quantum gates [Lim et al., Phys. Rev. Lett. 95, 030305 (2005)]. Afterwards, the...
