discuss Integral Holography

[dannybee]

There are a couple ideas that go way back to Gabriel Lippmann idea of a camera
I've always wonder about building a camera based on this idea and using the lens and the transparency for the object retaining full parallax in the view
copy from http://en.wikipedia.org/wiki/Integral_imaging
"An integral image consists of a large number of closely-packed, distinct micro-images, that are viewed by an observer through an array of spherical convex lenses, one lens for every micro-image. The term “Integral” comes from the integration of all the micro images into a complete three dimensional image through the lens array. This special type of lens array is known as a fly's-eye or integral lens array; see Fig. 1.
Figure 2: Integral image (Left) without lens; Enlargement (Center), note that each lens records its own unique picture; Integral image (Right) resolved through a matching lens from a particular viewing position; Roberts & Villums.

a another idea out there is "When properly practiced, the result is credible three-dimensional imagery which coveys a realism similar to holograms. Indeed, it has been demonstrated that an integral image can very accurately reproduce the wavefront that emanated from the original photographed or computer-generated subject, much like a hologram, but without the need for lasers to create the image; see Fig. 2. This allows the eyes to accommodate (focus) on foreground and background elements, something not possible with lenticular or barrier strip methods."

and i-Lumogram rendering http://www.geola.lt/lt/download/programs_and_manuals/ only has horizontal parallax ... Ive see a few of this and I was not Impressed... but do see how they are good for large displays but still lacking full parallax

where to buy the lens http://www.ntkj.co.jp/product_flyeye_en ... oduct_spec
hummm maybe you could use 2 lenticular sheets one for horizontal and one for vertical mounted on thin glass

Stacked lenticulars can work in theory, but you'd have mount the top one with the lenses down to get the integral image at the focal plane.
