I think it has real advantages. Firstly, depending on how you proceed, and if you decide to build a custom system you can potentially use VERY bright light sources... far brighter than anything that a projector will produce. Second, you can sync the output to your cameras as well, or to a trigger delay... that opens up many possibilities in respect to scanning. On the downside, it takes a good amount of experimentation to land on a solution that will work for you. That said, I believe that a strobe driven speckle projector has a lot of real advantages. At the very least, it's worth having a go! Up till now, it's sort of been one of the "secret" weapons in my toolbox. Like I said, I've not specifically tried this unit, but works on exactly the same method as what I cooked up here.
Cheers,
