Hi!
I study photonic engineering. My current main interest is in physical phenomena, including Fourier optics, holography, light sources (e.g. lasers) and optical components (e.g. LCDs).
What do you think of a non-invasive brain interface?

Preferred programming language: C/C++
- Once I learned something about OpenCL, OpenMP, Qt,.....
Favorit operating system: Xubuntu/Win/Mac -> Cross-platform
Favourite musical instrument: Didgeridoo
Nice to be here.
@MaxDH hello and welcome to the #QOTO instance and community! Thanks for the TED talk also, I have yet to watch this video and hopefully I'll get a better understanding of some of the things you're interested in. Can you share some of your thoughts on #photonics as it relates to spacial computing (i.e. Magic Leap)?
@absolutus
Thank you for the warm welcome =)
My first thought was, how does the display work?
I found a patent from Magic Leap, Inc.
Maybe the Magic Leap One works like this =)
In order to obtain a real 3D image, it is necessary to create a light field as if from a real object.
This can be done by modulating the wave field, e.g. as a sphere, Fig. 2A[pat].
When we "see" such a spherical light field, it looks as if it comes from a (virtual) point source.
The patent describes the stacking of the light-guid optical elements to a 3D display (WRAP), see Fig. 5A[pat].
By using a beam deflector, any 3D pixel can be addressed. The result is that the calculated virtual environment can be projected into the wearer's eyes.
Some interesting points of the patent
- Section 0034: limited number of slices of a 3D volume ("...less than 16 to 36 or more...")
- Section 0036: How is the light field generated?
- Section 0048 ff: WRAP device
- Section 0052 ff.: How the WRAP works (in particular section 0055f)

Please correct me if I’m wrong.
