Maybe I’m too cynical but I imagine this is a mechanical rehash of some actual human’s actual hard work.

At the very least, it's SEO drivel written up by somebody who does nothing else than that regardless of topic, and is paid by output (or ad conversions, ideally).
I've come across this type of text whenever I was diving into a well-researched practical tech topic that I had previously no clue of: 3d printers, HVAC plumbing, car repair. It seems that the topic must be basic enough to attract lots of people, but still valuable enough to be worth the hustle.
Frankly I like that this is what search engine spam is becoming: almost usable, almost informative, at the very least good enough to teach you the words to define your next search ...

Thanks for the audit.
Recommendations for an intro article on the same topic would be appreciated. There are lots of complex and/or vendor articles.

Of light?? How fast does the air have to be moving or do your sensors have to be?

Light interacting with particles in the air, https://ntrs.nasa.gov/api/citations/19910009744/downloads/19...
> A laser anemometer measures fluid velocity indirectly by determining the speed of particles moving through the flow field. These particles, which may be occurring naturally or introduced artificially into the flow, must be sufficiently small so that they follow the flow closely. If this is the case, then the fluid velocity can be equated to the measured particle velocity.

It doesn't have to be very fast. Doppler shift causes the return signal to be a different wavelength which can be accurately detected interferometrically even if the shift is very small.
