Liquid crystal refers to a special chemical compound that lies at the heart of this innovative technology. But we'll get to that in a second. First, let's talk about digital images. Every digital image -- LCD displays included -- is composed of millions of individual pixels, the name for smallest visible unit of the image. On a color LCD display, each pixel is broken down into three subpixels. These subpixels are each assigned a color: red, blue or green. The different colors that you see on an LCD display are produced by controlling the intensity of the light available to each red, green and blue subpixel. The way LCD displays control how much light is available to each red, green and blue subpixel is through teeny-tiny particles called twisted nematic phase liquid crystals. Twisted nematics get their name because they are twisted in their natural state. But when you apply an electronic charge to a twisted nematic crystal, it untwists. Like backscatter X-ray machines, millimeter wave scanners produce detailed full-body images of passengers, but they do it with ultrahigh-frequency millimeter wave radiation rather than X-rays. If you went on name alone, you might think "advanced imaging technology machines" could help doctors hunt for tumors or other medical conditions. In reality, the label -- euphemism, if you're cynical -- adopted by the U.S. Transportation Security Administration (TSA) describes the whole-body scanners found at airports that detect weapons, explosives or other threats being carried on passengers. According to the TSA's Web site, the agency had installed 800 advanced imaging technology machines at 200 U.S. November 2012. The machines come in two flavors, based on the type of electromagnetic radiation they use to make a scan. Backscatter machines -- about 30 percent of the installations -- send low-energy X-rays to bounce off a passenger's body. Millimeter wave (mmw) scanners emit energy more akin to microwaves. Both see through clothing to produce a 3-D image of the person standing in the machine. estados unidos coronavirus
