... intersecting the axis of the rotational mount. By using the optical lens, focus the beam onto the rear plane of the prism which can be rotated to vary the angle of incidence. The prism coupling assembly should be fixed to the rotational stage in the orientation as shown in Fig. 3b. The laser orienta ...

Shaping the focal intensity distribution using spatial coherence
... Although light encountered under many practical circumstances is partially coherent, the intensity near focus of such wave fields has been studied in relatively few cases [1–5]. The correlation properties of focused partially coherent fields have been examined in [6,7], where it was shown that the c ...

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.
