DOC OK: Lighthouse Tracking Analysis


#1

Interesting reach about the Lighthouse tracking accuracy and the sort:


#2

It is an elegant design. The deep analysis shows the lasers are modulated with 2MHz signal. They say it is done to help the sensors disambiguate the beam from other IR sources, but I think there is more in the works with newer lighthouse units. If the 2MHz modulation encodes an ID and the sensor ASIC is upgraded to decode those IDs, it means many lighthouses can be set up without having to do the token passing presently done today. So, many lighthouses and no interference. By far, this approach is oodles superior to the Rift approach.
