What is this "Spatial Phase Module"?

[Xytrell]

Does it work, or do they just have the before and after pictures mixed up?

If it does work, how does it work?

Could well be that it works. It just adds a random phase to the laser beam, which is different at each position and fast modulated in time. In that way the beam looses spatial coherence and with it the ability to create interference. This is often alse done just with a fast spinning diffuser plate.

Its data-sheet mentions a patent no, clearly discribing it's internals

uh it's the same just with a holographic phase plate. Incredible that this can be patented!
