Michelson–Morley @ Home
The Michelson-Morley experiment seems to have taken many years, resources and a nervous breakdown to complete.
Is it possible to recreate a variation of this experiment at home for say, under $1000, ...

How does a warp field interferometer work?
Assume I have a solid grasp of undergraduate physics. From what I've read the warp field interferometer is supposed to be a sort of Michelson interferometer, except instead of adjusting the ...

Why does heterodyne laser Doppler vibrometry require a modulating frequency shift?
On the wikipedia article (and other texts such as Optical Inspections of Microsystems) for laser Doppler vibrometry, it states that a modulating frequency must be added such that the detector can ...

Image contrast as function of exposure for a CCD detector
In a laser interferometry experiment, we project a pattern of interference fringes onto a CCD sensor. For best results, we want good contrast between the bright and dark fringes, and we carefully ...

Does a FTS work on the same principle as a michelson (amplitude division) interferometer?
As far as I can tell within an Fourier Transform Spectrometer the spectral information is gained from changing the path length along one arm, this sounds very similar to a michelson interferometer but ...

How is the Hanbury-Brown and Twiss effect used to measure the size of stars?
I understand what an Hanbury Brown and Twiss (HBT) interferometer does, but how can this be used to measure the apparent angular diameter of some object?
What is the mathematical explaination?

In interferometry, what is the origin of the name “Airy function”?
In interferometry (specifically, in the domain of Fabry-Perot cavities), the function $$f(\phi) = \frac{1}{1 + F \sin^2 \phi}$$ , which describes the shape of the resonant structure of the cavity, is ...
