Narrative:
We were at 100 feet AGL on the ILS 3R CAT ii approach to landing in dtw when we hit wake turbulence from an MD80 that had landed before us. The left wing suddenly dipped down. I was able to correct it almost immediately but it scared me; considering this occurred at ~100 feet AGL. When I had the aircraft corrected and stable I was already over the runway and decided to continue to land; since I was probably only 50 feet over the runway and the aircraft was stable again.the wind was absolutely calm; 0 knots. Touchdown zone RVR was 1400 feet; mid RVR was 1200 feet; in heavy fog. During the approach; we were following an MD80 at 3 NM. I believe that this separation may not have been enough separation for a CAT ii approach to prevent a wake turbulence encounter with calm winds.I think that ATC should have separated us a little further apart during this approach and under these conditions. Maybe 5 NM separation would be a good idea.
