Hi,
I'd like to learn of this effect of Heineken logo doubling be made with a diffraction grating after a scanner set?
Otherwise - is it a projected slide ?

scan the logo thru a diffraction grating.

What kind (name) of grating ? Does logo (=scan angle) need to be very small ?

It may well be a Gobo.
If you scan graphics through a grating you will indeed end up with multiple images of it. I think the size of the image will be roughly the same as the original (non-diffracted) image, so it will need to be pretty small.
As for the grating I think it's a "burst" or matrix type. You can also combine two linear gratings.

It is a grating.
Probably a very high quality burst grating from Laserworld, Dr Peter Meyer:

You can also have custom ones made with software and electron lithography and Peter does that as well.

Oh my- the pic on that link you just posted is INCREDIBLE!
I WANT!
Well, since this is a grating effect the nice looking effect would be rotating the logo during scanning as this would result with each logo rotating around own local axis - I bet this one would be great !
However it keeps bothering my mind that since the angle between 0th and 1st order beam after the grating is pretty small, while the logos displayed aren't touching each other - the initial scan angle should (must?) be VERY small... or am I missing something ...

Here's some examples of graphics scanned through gratings - some nice stuff:
