RAY OPTICS
... According to (1.2-2), rays that are emitted from a point very far out on the z axis (zi = 03)are focused to a point F at a distance z2 = (-R)/2. This meansthat within the paraxial approximation, all rays coming from infinity (parallel to the mirror’s axis) are focused to a point at a distance ...

... which is due to the light ray path depicted in Fig. 1.4, stretches out over a relatively large area. The latter has the shape of an iris stop (the iris diaphragm consisting here of five blades), and exhibits much lower intensity than the in-focus reflection. For a rotationally symmetric camera lens, ...

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.
