As Royi says in their comment, the main forum where you originally asked this question is probably the best in the Stack Exchange family for the topic of 3D Reconstruction. Where it's possibly not a good fit is the part where you say ideas can be tossed around, critiqued, argued. The reason is that this side is a Question and Answer site. Depending on how ...

You're right, these are synonymous. I've created a synonym suggestion, and users with a few answers on the tag can vote for it. I believe since this is really just a matter of expanding an acronym, a moderator might be able to expedite the process.

cycles/sample is correct, and it is not unitless. In those units, the Nyquist frequency is 0.5.  In units of radians/sample, the Nyquist frequency is $\pi$. The Matlab functions I'm familiar with use units of cycles/half-sample, and the Nyquist frequency is 1.0.

Hertz particularly refers to time rate of some repetitive event such as rotation. Whereas Cycles per length refer to space rate of some repetitive event such as a picture line bar pattern. Cycle simply means a repeating event, mostly a whole rotation of something, or a $2\pi$ increment in a sinusoidal argument. In most contexts, the word cycles can be ...

I speak with no authority on this subject but interest in what the answer is- I found this table pasted below at this link https://www.sciencedirect.com/topics/engineering/units-and-dimension#:~:text=Dimensions%20are%20physical%20quantities%20that,relative%20unit%20that%20describes%20length). Which lists the radian as a unit, but doesn't have a fundamental ...

I believe the confusion can be explained as semantics, specifically the word "cycle" or "cycles". In the context of signal frequency, such as the Nyquist frequency, it refers to one period of a continuous periodic signal. And in the context of sampling, such as the Nyquist rate, Fat32 equates it to $T$, the sampling interval. If we ...

This question wasn't really about the units of frequency. The notion that a standards committee could hijack a common word, claim it as their own, and forbid other uses of it, is so arrogant and hubristic that it boggles my mind. I don't care if it happened 60 years ago (about my age) or yesterday, what is wrong is wrong and when that is recognized if ...
