MIT Media Lab publishes a IEEE Access paper "Rethinking Machine Vision Time of Flight
With GHz Heterodyning
" by Achuta Kadambi and Ramesh Raskar presenting "time-of-flight imaging that increases its depth resolution 1,000-fold. That’s the type of resolution that could make self-driving cars practical... At distances of 2 meters, the MIT researchers’ system... has a depth resolution of 3 micrometers."

The paper presents an indirect ToF imaging with a GHz modulation frequency:

A Youtube video explains the group's achievement:

Thanks to DS for the pointer!
