• Polarization-maintaining optical fiber — In fiber optics, polarization maintaining optical fiber (PMF or PM fiber) is optical fiber in which the polarization of linearly polarized light waves launched into the fiber is maintained during propagation, with little or no cross coupling of… …   Wikipedia

• Point source — For other uses, see Point source (disambiguation). A point source is a single identifiable localized source of something. A point source has negligible extent, distinguishing it from other source geometries. Sources are called point sources… …   Wikipedia

• Circular polarization — The electric field vectors of a traveling circularly polarized electromagnetic wave. In electrodynamics, circular polarization[1] of an electromagnetic wave is a polarization in which the electric field of the passing wave does not change… …   Wikipedia

• Circular polarization in nature — Only a few mechanisms in nature are known to systematically produce circularly polarized light. In 1911, Albert Abraham Michelson discovered that light reflected from the golden scarab beetle Plusiotis resplendens is preferentially left handed.… …   Wikipedia

• Orthogonal polarization spectral imaging — is a method for imaging small blood vessels[1] in tissue like the nail bed or lip. It uses a light source of linearly polarized light with a wavelength of 550 nanometers, the isobestic point for hemoglobin, thus imaging the erythrocytes as they… …   Wikipedia
