It's quite a mystery which kind of proximity fuse Iron Dome's Tamir missile is using. On some photos, there's no slightest sign of laser sensors on a missile...
In any case, use of laser proximity fuse in a missile designed for engaging such targets as small rockets is surprising, to say the least: the small object may simply fell between the two narrow laser beams.
I know nothing about laser proximity fuses. But as a guess, surely it's possible that a laser fuse could be sending out light in a fan shaped pattern, and not a bunch of thin beams?
