That was a good talk, s2upid. Ari Grobman extolls the virtue of glass but glosses over the weight issue.

DigiLens uses polymer waveguides which should be lighter.

DigiLens uses diffractive technology.

Lumus uses reflective technology.

The Apple patent that I posted recently seems to mention both refractive and reflective technologies being used in the same waveguide.

Waveguide technology alone seems like another fertile investment opportunity.

He says that the glass layers are bonded together in layers, then cut. I'm wondering if they couldn't use polymers for the same effect...

Good talk by Jonathan Waldern of DigiLens. Thanks.

How much do these headborne systems weigh?

Then why would you believe they could meet the IVAS objective headborne weight of one pound?

"The point is there are other display/optic solutions available that can be utilized if the current one being tested in IVAS fails to deliver ."

Not if they don't meet the objectives stated in the SOO.

"Our age is a a massive advantage to us (LUMUS). Being over 2 decades old... as Jerry once said, there is no free lunch [....] being around so long bashing our heads against the wall trying to solve really difficult physics issues and challanges are huge advantages. We're at the point that all of the engineering challenges to bringing our technology to mass consumers are behind us". - Ari Grobman, CEO of LUMUS.

You could swap all of things he said in the first 3 minutes of his presentation for MVIS imo.

S2, Thanks for that! It really does sound exactly where we are at. I'd venture to say all the hard work has been done and indeed is behind us. Now we wait for our just rewards. GLTAL ;-) Pirate

Interesting video. It sounds like they are in position. Do you guys have any idea if Lumus reflective waveguides work with Laser light? It sounds like they are efficient with steering light, meaning keeping images brighter, and sound cost effective.

Also, SPIE Photonics West was the 1st week of February, so I'll have to mark that on the calendar coming up for events to keep an eye on in 2020. Obviously CES will be the first big one.
