Magic Leap – The Display Technology Used in their Videos

So, what display technology is Magic Leap (ML) using, at least in their posted videos?   I believe the videos rule out a number of the possible display devices, and by a process of elimination it leaves only one likely technology. Hint: it…

Celluon/Sony/Microvision Optical Path

Today I’m going to give a bit of a guided tour through the Celluon optical path.  This optical engine was developed by Sony probably based on Microvision’s earlier work and using Microvision’s scanning mirror.   I’m going to give a “tour” of…
