I would tend to agree and why I put it in quotes in my article. It it is not as egregious as M/S Hololens calling what they are doing "Holograms" and everyone knows it but they are all calling mixed reality objects Holograms now. At least the focus planes are doing something similar to Light Fields.
Similarly it looks like Avegant is calling what they are doing "Light Fields" because Magic Leap was calling Focus/Focal Planes "Light Fields".
Loosely conceptually, Light Field work in the horizontal direction relative to the light rays from the image source, where Focus Planes work in the vertical direction.
I have not done much with Light Fields personally, but Nvidia has published some good work about them (https://research.nvidia.com/sites/default/files/publications...) using what I would call "classic light fields." Gordon Wetzstein has presented how to do light fields with much fewer sub-elements (https://www.youtube.com/watch?v=itSjM_OzVtA) and there is a lot of other material out there on "compressive light field displays" that he has been working on for a long time. He claims to get decent results with just 2 fields. BTW, I highly recommend reading about everything I have seen from Dr. Wetzstein, he does an excellent job of explaining complex optics concepts.
