POLARIZATION OF LIGHT
... Consequently, two coherent plane-polarized light waves whose planes of oscillations are mutually perpendicular produce an elliptically polarized light wave when superposed on each other. At a phase difference of zero or π, the ellipse degenerates into a straitght line, and plane-polarized light is ...

Since the fibre is very thin, the light beam inside strikes the interface at a large angle of incidence, large enough that it is reflected back into the glass and is not lost outside. Thus fibres can guide light beams in any des ...

Interferometry
Interferometry is a family of techniques in which waves, usually electromagnetic, are superimposed in order to extract information about the waves. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, and velocimetry.Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities. In analytical science, interferometers are used in continuous wave Fourier transform spectroscopy to analyze light containing features of absorption or emission associated with a substance or mixture. An astronomical interferometer consists of two or more separate telescopes that combine their signals, offering a resolution equivalent to that of a telescope of diameter equal to the largest separation between its individual elements.
