Hello,
I was hoping to design a pair of AR glasses for a school project, and I had some questions after reading the DLP technology for Near Eye Display app report (attached here: https://www.ti.com/lit/an/dlpa051a/dlpa051a.pdf?ts=1598833896793&ref_url=https%253A%252F%252Fwww.ti.com%252Fdlp-chip%252Fdisplay-and-projection%252Fpico-chipsets%252Fapplications.html )
1) Is waveguide essentially a special type of lens? Does it replace the "Optical System" block in figure 3-1 of the app report?
2) In figure 3-2, what are the "eye-piece optics"? Do the dimensions of these lenses matter?
3) Does distance from input to output of the waveguide matter (based on figure 3-2)? (i.e. after projecting an image on the waveguide from a microdisplay, is the image visible anywhere and everywhere on the waveguide, or does distance matter?)
3) Finally, do you have any recommendations for waveguide manufacturers? What would the estimated cost range be for a glasses-sized waveguide? What are other options for the "Optical System" block in figure 3-1, other than waveguide, that are compatible/work well with TI's DLP products?
My constraints for this project are time (~3 months) and money (~$600 budget). Any help is appreciated.
Thank you,
Jerry Liu
