Fiction turns reality now as you can use the latest technologies to see through the walls. The credit for the development of the technology goes to Gregory Charvat and John Peabody of MIT. The only condition is that you must be standing a little away from the wall and you get the view of the activity going on on the other side of the wall.

There are some 21 antennae in the device arranged in two rows. The upper row works for receiving the signals and the lower row does for reflecting it to you. All the antennae are mounted on a moving cart. It makes the device quite handy.

The device may be useful for dealing with the criminals in the urban conditions; though the implications are important for the military as well. Take it as a limitation or so, but you have to be some 60 feet far from the wall and the device will bring you the video of the activity beyond the wall with 10.8 frames per second. It is the greatest plus point of the device as the real time value of the device comes from it.

Earlier the speed could not be attained with the laser as the 10000 times amplification of the scanty rays that could eventually cross a few- inches-thick concrete wall took a long time even with efficient amplifiers. This is the least resolution needed for making it of any practical use.
