... This laboratory is to show that the very simple principles of reflection and refraction can lead to sophisticated ideas about optical instrument. We begin with a ray box that has a slotted mask in front of a light bulb to produce a set of thin beams (or "rays"). The rays lie along a plane surface (a ...

Towards a lattice based neutral magnesium optical frequency
... Magnesium is an interesting candidate for a future high performance neutral atom optical frequency standard. It offers low sensitivity to frequency shifts of the 1 S0 to 3 P0 clock transition by room temperature blackbody radiation and several isotopes of suitable abundance (two bosonic, one fermion ...

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.
