Bessel Beam Theory - u.arizona.edu
... Diffraction is a feature of the wave nature of light. It can occur anytime a beam of light passes through an aperture that is large with respect to its wavelength1. According to the Huygens-Fresnel Principle2, every point of the wavefront that is unobstructed by the hindrance serves as a source of s ...

... when the lens is submerged from air into water. The mirror forms images by bending light rays by means of reflection. For each light ray involved in forming the image, reflection occurs at the curved surface of the mirror. By Archimedes’ law (Θ̄ = Θ), the angle of reflection (Θ̄) for each light ray ...

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.
