#1 Isn't this a spin off of the Zionist Death Rayâ¢?

Muslims will never allow it then.

#3 Will they destroy the terrorists upon detection?

#4 BD, you just turn the dial and they are cooked in thirty seconds with the added benefit they glow in the dark. I've heard that Muslims cooked this way, taste just like pork.

#5 The frequencies between infrared and microwaves are usually called millimeter waves. In college I worked with a professor who was developing a milimeter wave system to image hidden weapons about 30 years ago. I am not sure how this "terahertz" stuff differs from these millimeter wave systems that have been around for a while.

#6 This technology has been around for about 10 years. It's another reason why Bell Labs were a national treasure.

The researchers used laser pulses each lasting only 100 femtoseconds (one tenth of a trillionth of a second) to generate, detect, and measure electromagnetic pulses -- T-rays -- each lasting a picosecond (a trillionth of a second).

They transmitted the T-rays through various objects, using an imaging system of lenses and mirrors to focus the signals and to analyze changes in the T-rays as they passed through the objects.

They characterized the materials by measuring the amounts of distortion -- from absorption, dispersion and reflection -- of the T-rays passing through to a detector. Those going through the lean portions of a slice of bacon, for example, are distorted into a different waveform than are those passing through the fatty portions.

A digital signal processing unit processes the data and translates it into images that appear on a computer screen.

The image of a slice of bacon shows different levels of T-ray transparency for lean and fatty areas. Since fat absorbs almost no T-rays, it looks white; meat absorbs roughly 25 times as many T-rays, so it looks dark.

The digital signal processor was programmed to recognize the characteristic shapes of transmitted waveforms and identify the particular material at the spot illuminated by the T-ray beam. This information was obtained for every point or "pixel" on each object.
