Any help figuring that out would be appreciated, even if only to provide some search terms to better define the lenses (I improvised the term "nodal lens" to indicate the lens/mirror with one vertical line of symmetry, but without a radial profile). 88-inch wide interactive touch screen - Operated by Pen (stylus, or an electronic pen) and Finger Touch - Multi-touch gesture support (for scroll.
Details: short, throw, projector, hitachi, starboard, ultra, motorised, mobile, board, trolly. This is probably going to be the result of years of devoted optical engineering and development as well as expensive & precision optics- however I'd like to learn more about what principles are at work here as an alternative to the Scheimpflug principle I was attempting to leverage on my last go-round. Hitachi StarBoard FX-DUO-63 inch Smart Board various adjustments allow projection more application and viewing flexibility. Unfortunately I'm not allowed to take it apart- but the optics I can observe externally illustrate what appears to be a fisheye lens projecting through what appears to be a nodal lens of some sort, and finally reflecting off of another convex nodal mirror before arriving flatly and in focus on the entirety of the screen. This projector overhangs a white screen, and projects a large, high resolution desktop onto it with a very focused, and balanced image. We have Hitachi's starboard projection system- which is a pretty neat gadget in itself, but what's prompting this question is the unique optics involved.

That particular item has recently come back to me for development and I'm curious about a recent technology that we have observed in our very own conference room. The Ultimate Short Throw series provides high performance projection in small spaces.
I'm the guy who posted a thread back in '08 regarding acute angle projection & the Scheimpflug principle.
