Polarized light reflectometer.
The modulated reflected and nonreflected light fluxes, measured as the azimuth of incident linearly polarized light is varied, yield the absolute reflectances R(p), and R(s), of a dielectric or semiconductor surface. Application to a reflective Si detector determines the refractive index and thickness of a SiO(2) film on the detector surface.
متن کاملPolarized light microscopy.
Polarized light is the light in which all the rays vibrate in one plane. A polarizing microscope has two disk accessories. They are made up of polarizing plastic that allows light vibrating in one plane to pass. One of them is called a polarizer (placed below the condenser). Another similar disc is placed in the top part of the microscope and cuts off all the light vibrating in a perpendicular ...
متن کاملInteraction Matter-Polarized Light
This chapter presents the process of interaction of light, mainly in the xray range, with matter. The subject is introduced by some experimental evidences of x-ray absorption, emission or scattering by different kinds of material. The ways of describing the electromagnetic wave field are then briefly presented before developing its interaction with an electron in an atom. This process is then a...
متن کاملHandling Polarized Light
As we discussed earlier F (x, y) is nearly independent of the things that matter in propagation and we may ignore it in what follows. We also assume that the instantaneous polarization (direction) of ~ E(t, z) is independent of the position inside the beam (namely, it is independent of the x, y coordinates) thereby implying that we are treating the propagating field as a plane wave. This is kno...
متن کاملPolarized-light navigation by insects.
T he eyes of insects are sensitive to a natural phenomenon that man is blind to: the polarized light of the daytime sky. It is this capacity that under lies the remarkable navigational ability of many insect species. Exactly how can an insect navigate by polarized light? To ask this question is really to raise three separate questions: What makes the visual cell of an insect sensitive to polar...
