do you know if the thickness of the slats or the space between them affects the diffusion properties at all?
Thickness is one way to have a fairly stiff slat. (EDIT: Theoretically, amplitude grating diffuser will work even with thin slats)
Space between them? Space is regular "zero" in binary sequence, so, yes, it affects diffusion...

......... Is this type of diffusion effective on smaller panels?
I doubt that, phase grating diffusers in smaller panels, performs better

I never accept this type of (couple of smaller panels) approach because it is fully ineffective for the SBIR or non resonant interferences, which degrade frequency response at listening place. So, binary diffusers is useful for me to bring back reflections to the listener after I install low frequency trapping over all walls and ceiling, and this is a reason why I treat whole wall (smaller surface is not enough, because room is too dead after only LF treatment)... and this way they are effective and I can share my experience about that. Smaller panels influence can be audible, but this is not the whole goal. First goal is to solve dips in frequency response (non resonant interferences below 200Hz), together with room resonances (resonant interferences below 200Hz), as best as possible... after that... it's about personal preferences....
