hello how to implement phase singularities in arduino. thanks very much.
Do you have a Shack-Hartmann wavefront sensor?
sorry I am not sure what is meant by context. I don't have a shack hartmann wavefront sensor. I am trying to implement optical phase singularities using wavelets and arduino. thanks.
That is "context".
what is an "optical phase singularity"?
You will need a fairly powerful Arduino (or Arduino-compatible) to do image processing.
i worked on displacement measurements in speckle grams using an phototransistor, stepper motor and apple II computer in college (see automated fringe measurement ...).
doubt that's what he talking about
Although rare in most localities, it is remotely possible that an intrepid Arduino enthusiast/experimenter might encounter an unusual phenomenon associated with an optical phase singularity. In such cases, a Shack-Hartmann wavefront sensor would indeed be handy.
Wikipedia clarifies this concept as follows:
Implementing an optical phenomenon takes optics, not electronics. Can you clarify what you are trying to achieve and where electronics and image processing fits in?
Moderator: this surely belongs in the science and measurement section?

this is an example paper. Fringe Pattern Analysis in Wavelet Domain | IntechOpen thanks a lot.
What do you have in mind for the Arduino to do?
to generate phase singularities or fringes from an rf antenna wireless communication circuit.
An unusual, and especially challenging Arduino project. Let us know how it goes.
Microwave, I assume. How much power is involved and what bandwidth?
a basic transmitter circuit probably containing a sensor. 10 to 15 meters transmission should be adequate.
I am implementing phase singularities in order to generate wormholes, and ultrabroadband invisibility cloaks on the arduino.
Fringes have only been detected for microwave frequencies as I recall.
this paper describes invisibility cloaks at different frequencies https://arxiv.org/pdf/math/0611185.pdf
