The only part that I think could be debated is my assertion that it’s single module. While technically the illuminator and receiver are different components manufactured by different vendors, they are integrated into one module well before final assembly - and generally when you buy ToFs from semiconductor manufacturers, you get a single mostly rigid part that has everything attached to it.

I suppose I could also imagine someone challenging my assertion that industrial 3D scanning uses structured light, because there are some vendors that use -temporal structured light-, where you flash different patterns to resolve different spatial frequencies on a stationary part. But beyond that I am as confused as you are.
