Michelson interferometer but with 1 arm (Part 2)

I designed a setup similar to Michelson Interferometer but with one mirror only. So, there is an angle between the 2 rays to the detector: In order to understand the result on screen, I used (Zemax/...

Interferometer designed to create diffraction in free space

I designed the following interferometer: If the light beam -theoretically- is very narrow , will light be diffracted away from point B from QED's perspective?

Why do two-beam interferometers have a relatively broad "fringe width" compared to single-beam interferometers?

I recently overheard someone discussing the basics of interferometry setups. They said that two-beam interferometers have a relatively broad "fringe width" compared to single-beam ...

Do interferometers require polarizing beam splitters, or do they require non-polarizing beam splitters?

I want to build an interferometer. In order to do so, I need to buy some optical components, such as beam splitter cubes. These beam splitter cubes, and other optical components, come in a polarizing ...

Interferometry: effect of aspheric lens on self-mixing effect

I want to perform self-mixing interferometry experiments using a laser diode, as was done here. I'm going to use a low-power laser diode. However, I want to improve the performance of the device, ...

What is 'optical phaseshift'?

In interferometry, it is said that lasers can be used to measure the 'optical phaseshift' of something. I am familiar with the concept of phase in the context of waves, but I don't understand exactly ...
