Mechanically, the 1.0 system uses 2 rotating lasers and an IR strobe, so the sensors have to be able to read the IR strobe for timing data. The 2.0 system uses a single rotating laser and embeds the timing data in the laser; since there's only 1 laser sweep and no pulse per cycle, they can have twice as many lighthouses running at once without causing interference with each other. It also reduces the cost of production and potentially increases the reliability of the lighthouses, since less moving parts and less points of failure.
