Phase difference in Michelson Interferometer
I'm currently taking a quantum mechanics course in university and our professor introduced us to the Michelson Interferometer (or at least what I believe is an apparatus based on it), where a light ...

Orienting birefringent crystal the right way in an interferometer
I'm working in a lab that involves transforming the polarization state of one beam of light in an interferometer via a Barium Borate (BBO) birefringent crystal. As the polarization state is altered ...

Calculating Coherence Length and spectral width given an interferogram
I'm currently doing a lab in which we use a Michelson-Morley interferometer to analyse different light source. One of the mirrors in the interferometer is moved by a stepper motor. One of the light ...

What does it mean for a light to have low-coherence?
I've been searching about OCT imaging and understood that it is based on low-coherence light source. The problem is, I don't understand what is a low-coherence light source. Based on what points that ...

What happens when light of two different colours interfere destructively?
In one of my lab courses, we are using an interferometer. I can understand how the interference works when it comes to monochromatic light, but for white light, I am unable to picture how the ...

Fabry-Perot Interferometer
let's consider a Fabry-Perot interferometer:
Illumination is provided by a diffuse source, and its rays are focused towards the cavity by a lens. Inside the cavity there are multiple reflections and ...

Michelson interferometer: beam division
so I'm working on the Michelson interferometer for a presentation, and I'm having trouble understanding how does the beamsplitter splits the incoming beam.
Let's consider the incoming bean as a ...

Why are the fabry Perot Interference fringe sharper than Michelson interferometer fringe?
Does it have anything to do with the fact that fabry Perot interferometer uses multiple beams while michelson only uses 2 beams

Michleson Interferometer fringe shift
I have a problem with interferometer fringe shift. I am learning it from my physics book. In the book, it is written,
"As the L1 (Displacement of moveable mirror) is changed, the pattern of ...
