The older IMAX digital used two Barco DLP projectors (proper three-chip DLP, not colour wheel crap) slightly offset from each other, but that should be mostly phased out by now.
"Should" and "mostly" give no solace to those of us stuck waiting for the local IMAX screen's older digital projectors to finally conk out so they'll finally upgrade. They've got a full height 1.43:1 screen dating back to the 90s but dragged their feet so long on upgrading from analog to digital that if they'd just waited one more year they could have gone straight to second gen digital, but NO they upgraded at the exact wrong time to do so leaving us stuck with a projection system that can't actually fill the whole physical screen... (IIRC 1st gen IMAX digital can only do 1.9:1, second gen can open up to full 1.43:1)
