Question about Michelson Interferometer
In Michelson Interferometer, the mirror that lies in the middle (half-silvered mirror), can reflect and let through light. But the light after being reflected by the half-silvered mirror, only let ...

Phase shifts in different beam splitter designs
I am trying to understand how a Mach-Zehnder interferometer works. It seems that it will work whether we use two beam splitters that consist of either
glass prisms glued together
a sheet of glass ...

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, ...

Path difference between rays in Michelson interferometer with inclined mirrors
If mirrors of Michelson interferometer are inclined the resulting configuration is the one in picture (tha analogy is with the thin wedge) where ray appear to come from $O$. If the distance between ...

Why does this wavemeter use $3$ mirrors to turn light $180^\circ$ instead of just $2$?
In this geometry of wavemeter, why do we use 3 mirrors instead of just 2 mirrors positioned 45° to each other to turn the light beam 180° around?

Michelson interferometer beam splitter phase shift
In a Michelson interferometer (image from Optics by E. Hecht ) .
To quote from the same book:
As the figure shows, the optical path difference for these rays is
nearly $2d \cos 0$. There is an ...

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 ...
