AI Thread Summary
Creating a holographic projecting lens involves understanding the principles of holography, which captures light fields to display three-dimensional images. The discussion clarifies that Google Glass does not utilize a holographic lens, as it primarily projects images using standard optics rather than holography. For those interested in replicating Google Glass, there are accessible online guides available that provide step-by-step instructions. The conversation emphasizes the need for clarity in terminology regarding holography and its applications. Overall, the focus is on the feasibility of creating similar technology independently.

What would it take to create a Holographic projecting lens? Ideas and Procedures are appreciated.
Thank you.

What's a holographic projecting lens? For what purpose are you hoping to use said lens?
 
Okay I'll use simpler terms.
What would it take to recreate Google glasses? Alone.

What's holographic about google glasses?
 
Google Glass doesn't use a "holographic lens," I think you may be misinterpreting the meaning of the term. Take a look here: https://en.wikipedia.org/wiki/Holography

Wikipedia.org said:
Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics.

The good news is, there are step-by-step guides online for creating a home-made version of Google Glass, see here: Instructables: DIY Homemade Google Glass
 
Oh thanks a lot... Much appreciated
 
I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
