Tunteeko naapuri minut?

Alla on listattu seinän läpi katsomiseen tarkoitettu laitteita. Osa niistä näyttää seinän (esim. betoniseinän) takana olevan ihmiset ruudukolla liikkuvina palleroina, osa pystyy näyttämään koko kehon ja jopa uloshengitetyn ilman. Yksi jos toinenkin kysymys minulla olisi. Voiko tuollaisia rakentaa kotikonstein, elektroniikkakomponenteista kasaillen? Onko vastaavia kehitteillä tai tutkittavana suomen yliopistoissa tai ammattikorkeakouluissa?

Most walls are fairly transparent to radar or radio frequencies.

DARPA expects the portable Radar Scope to look similar to this model and come out as early as this spring (2006).


Through-the-Wall Surveillance (TWS) (2003)
Advanced ultra-wideband short-pulse (UWB SP) radar technology.

New way to see through a wall (2006)
The Radar Scope gives the capability to sense through a foot of concrete and 50 ft beyond into a room. Weighing just a pound and a half, the device will be about the size of a telephone handset and cost about $1,000.

prism 200 - through-wall radar (2005)
This compact, portable and durable product uses advanced signal processing to highlight moving people and objects in cluttered environments, through doors or brick, block and concrete walls.

See-through-wall imaging using ultra wideband pulse systems (2005)
Surveillance/navigation systems presently used make extensive use of television, infrared, and other line-of-sight-surveillance hardware. However, these systems cannot tell what is happening or locate persons/assets on the other side of a wall, behind bushes, in the dark, in a tunnel or a cave, or through a dense fog. It is our objective here to develop a new sensor, based on UWB technology. A small, lightweight, low power transceiver or multiples that are based upon the fact that microwave frequencies can be optimized to penetrate nonmetallic materials, and providing very precise ranging information.

Engineers develop technology to see through walls (2007)
The device uses sound waves at a particular frequency and a series of algorithms in the computer software to capture images through a wall or door and create 3D images.

Xaver 800 (2007)
With the Xaver 800 you can rapidly and reliably observe one or more people in a room and continuously monitor their activities while positioned outside the room’s walls.

Bonuksena vielä yksi, joka ei ole tarkoitettu seinän läpi katseluun, mutta materiaalin sisään katseluun kuitenkin.

Advanced X-ray technology (2007, pdf)
Conventional X-ray technology is very useful for looking at the shapes or outlines of “what’s inside.” But now, Hamamatsu takes you a step further. Adding the ability to identify material composition. For example, to tell if an item is made of plastic or metal. And even what kind of metal.
