It came up on another board, so I`ll just copy paste my thoughts.

Basically it`s newspaper hype. It`s nothing new (IIRC a Japanese prof. was working on such thing for some years now) or it can work on that principle if you think about it (it probably works from a single angle, enabling some coolphotos - but what about different angles..?),

Not to mention most tanks nowadays use thermovision even in daylight, and I guess the sufficiently high powered projectors come with a nice big heat signiture, the projectors themselves are vulnerable to even trees and bushes the tank drives by... projectors are a dead-end.

The way I can see this thing actually working is by using those thin paper-like (or something like that) active display films Siemens was working on a couple of year back, the application idea being e-newspapers and HUDs in civillian cars. Still, there`s a problem with the angles..

how is it passible to put Projekters all over the tank?
or have i missed something out?

I think that someone is trying to develop a paper thin LCD type of film (like what you said) that could radiate a "real time" image. (LCD's don't give off heat) Concerning the problem of angles and moving perspective the answer is thought to lie in layered screens. Each screen would display a different image of the background as seen from a particular "angle off" the tank (sort of like the "3D" postcards one finds at giftshops...as you move the postcard back and forth the "3D" image appears to move) changing ones viewing angle of the tank would reveal a new screen, and would hide the previously one, giving the illusion of a fluid (moving) landscape as one moves around...

I think their is someone else working on a wafer thin display made of micro-LED's that might (somehow) find their way into this kind of technology...LED's radiate their own light and burn cold, but might be hard to layer.


MY question is: would the operator of the "cloaking device" (in the tank) have to set the distance and angle of the "boggie" (they are trying to hide from), and the relative distance of the objects seen behind the tank? I don't understand how the "cloaking device" would "know" how big the tanks "relative footprint" is against the background. EXAMPLE: if someone is 100 yards from a (hidden) tank and if their is a tree 20 yards behind the tank, the size of the tree projected on the tank would look wrong at 200 yards(it would be too small).Maybe some kind of "radar" could calculate the relative distance of objects "behind" the tank...
